To be honest, my opinion of the Island has stayed about the same since I originally played RE4. The Castle is my personal favorite segment of the game, I could write why that is but another time. The Island is the weakest of the three areas in my opinion, but not by some huge margin and I'd actually say The Island has higher highs than the Village, personally. just a weaker overall average.
While I like most of the scenarios in RE4, there are a few segments I just don't care much for, and most of them are on The Island. Both the Village and Castle had a couple rooms I don't care much for, but don't really dislike either (okay, maybe I don't like Salazar's Statue Room, not just because of the statue, but for some reason I really don't like the hand platforming fighting in that segment at all, but it's brief so it's whatever for me).
The Island has the most areas where I'm like, "Ohhh, this part, ugh." I actually don't mind most of it, but some of it is more dull than anything else in the game in my opinion. To give my personal breakdown...
-I actually like the Island's opening, the part where you walk through some caverns and into an almost guerrilla cliffside establishment and climb it. It throws a lot at you right when you arrive, and I like the sort of feel it gives. From the Gatling enemy that the area opens up with, the small laser puzzle, the climb in caverns with little enemy holding points, the cavern with the weird drawings and spikes, the cliffside enemies throw dynamite at, and the most casual Merchant in the whole game. I think it's a fun opening sequence and I usually have fun in it.
-I actually REALLY like this next part of the Island. It's one of the stretches of the game with infrequent enemies, but stronger ones in a closed-in space so a bit more intimidating, and they have a good mix of kind of comical and yet tense. This is the part that includes the Oven Man scene, the little almost food cellar area with some tables and cabinets to maneuver around as a few enemies fight, the door with enemies throwing dynamite that opens and closes, and this area concludes with meeting the first Regenerator, the optional Freezer pick-up, and I think it's a great climax to what is RE4's closest corridor segment in the game.
-Now it's this next segment that first starts to bother me. Yeah, the part where you pick up enemies like a toy grab machine and drop them in the garbage is a bit of fun (and a nice little consequence the ones you miss come to get you), but the next few rooms I just always don't look forward to going through. you have enemies rushing through doors at you, many have electric weapons to stun you or crossbows or some shit, the sort of annoying (yet usually not that deadly) Plaga 3 forms, the place outside Ashley's cell with a big mob including two armored guys, that for some reason REALLY annoying room with the staircase in it. Now, I actually really like the Iron Maiden encounter you have in the lab area, and the atmosphere of the communication tower is pretty nice and a change of pace in how quiet it is. But then you have to backtrack BACK through the rooms you just came through with even more enemies ambushing you... That bit is a bit too much for me. And then you get Ashley back, and you have to take care of enemies bum-rushing you in kind of closed-in spots while also protecting her, and that one room right before you get to the garbage chute where there's like two enemy spawn points so you have to fight two little hordes in a small room that come at you with stun rods... Not fun.
-Now, the next area is okay. It's the area with the dumpster and Iron Maidens, followed by the wrecking ball room, followed by kind of silent hallway with side rooms and Regenerators that can open doors. The Regenerator Hallway is my favorite, but the Iron Maiden dumpster area can be pretty tense, and the Wrecking Ball room can have its challenges but I like the dynamic and how you can either have Ashley or yourself handle the wrecking ball. Nice little section.
-Theeeen we get to the truck segment. I just don't like this part at all really. It's kind of silly, but I don't like how instant-gameover some of the parts are and the whole sequence doesn't really feel thrilling, just kind of ammo and health consuming.
-Next bit they cut down on enemies and we get a few more cinematic moments. Lose Ashley, have the famous QTE scene with Krauser, a couple little areas with only a handful of enemies but in tricky placements, then the Laser Hallway and Saddler's throne room you can sit in. I think it's one of the cheesiest chapters in RE4 but enjoy it for all of its cinematic QTE'ness, honestly.
-I really like the encounter with 'IT' actually, and the sort of atmospheric halls before and after it.
-I actually really like both the enemy campsite you get to eagle-eye before you go in it, and the following Krauser fight. Both are quite enjoyable.
-Then comes my personal least favorite stretch of RE4, the goddamn helicopter scene. Mike is humorous as a character, but I just never look forward to playing this scene. Have to watch out for Mike's bullets, enemies everywhere, kind of cumbersome design, and throwing gatling gun guys in open arenas, as well as pressing switches and waiting for Mike to blow shit up which makes it sometimes more of a patience game. My absolute least favorite bit of the game.
-The Bag and the Prison where you hear a Regenerator but don't know where it is immediately is actually one of the most horror-y things in all of RE4 and just feels strange to how dark that single corridor is and its design feels different from the rest of the game to actually give me a sort of claustrophobic feeling, so of course I like it.
-The final big enemy fight where the enemy runs off with the keycard is alright. I find it fun, but it's not a favorite encounter either.
-Likewise, the scene where you get Ashley again, a few big armored guys come at you, and you get the plaga removed and Saddler attacks in a cutscene but Ada guns him down. Feel pretty indifferent towards this area.
-I like the finale, the Saddler final boss isn't the series best final boss, but it's fun. I actually like the dorky escape sequence and the jetski it mostly revolves around.

Basically my opinion on the island, I think the problem is that while there's a few really good segments in it I like a lot, it also hosts my three least favorite segments in the game (Helicopter scene, truck sequence, before garbage chute enemy mobs in small rooms segment you also have to backtrack through), and a few rooms I think are just alright or indifferent towards, which is not true for me towards the Village or Castle. My opinion, of course.
Near the end of Revelations 2. The start was super rough, but it's turned into an enjoyable experience with tons of cheese to go around.
Looking at that graph, it's amazing that RE 4 turned out to be considered one of the best games of all time. According to that, it was rebooted at least five times and the final version barely took a year to make.
Oh god, that's brilliant! Wesker runs with his tail between his legs with a look on his face that says "I got fucked up! RUN!"
Seems you may have part of my opinion of revelations 2, the first episode I wasn't completely sold on but was alright, but I think it got better as each episode went on. That's just my opinion. I also like the finale of Revelations 2 quite a bit, personally.
RE4's development will always be interesting to me. I don't think they literally made all of RE4 in a short period of time, they obviously use a lot of the groundwork they had from the other versions. But yes, to design all of RE4 with what they had and really cram in making it from all they learned from the various versions in 1 and half years or so is impressive.
