Now that this is out.. Season Pass rating X/10?
Personally, I'd go with 8/10, as someone who liked the main game well enough (not flawless, but I found it enjoyable, some stretches of the game more than others) and appreciated the sheer variety of scenarios and ideas on display through the game's course.
The DLC, if you can believe it, go in very different directions of the main game, but still retain feeling like Evil Within. I guess if its worth it depends on how appealing the three pieces sound to you.
The first two are a mainly stealth-based campaign following Kidman, featuring some new enemies and mechanics away from the main game, but almost no gunplay, including new areas and some revisited locations. Has some good atmosphere, a bit jankier than the main game (hard to describe but not as tightly designed), but also I would say a really good (but a bit easy) horror boss fight that ends off the second DLC. Actually, I'd say the best part of both the DLCs are the boss 'fights'.
Then the third DLC is basically a first-person Evil Within arcade game where you play as The Keeper, which basically amounts to a boss rush against seven different bosses (and a hidden eighth boss) and some hub exploration/optional arena fights. The combat was satisfying, but not too difficult (with the exception of the hidden eight boss and the new game+ dungeon), but the bosses were varied and fun, and the files were a bit interesting to read as it goes more into the scene post-ending of the main game and gives a bit more personality to a number of the boss monsters in the main game.
I enjoyed all three for what they were, if yo want more of The Evil Within this isn't exactly it... It's more experimental and focusing in different areas than the main game focused, but I found them to be enjoyable different takes on the universe in the game.
The first two DLCs are about 2-3 hours long each the first time. the last DLC is about an hour long with additional time if you do the New Game+ stuff. There's also some cool Easter Eggs I know in the first and second DLC, and wouldn't surprise me if there were some hidden we haven't found yet in the third DLC.
Some people really didn't like the Kidman DLC with its focus on stealth and almost no combat, so I bet some people's ratings will be lower. Those two are in the love it/hate it territory where you may love it, may hate it, sort of like the main game but in a different way. Strangely I think the Keeper DLC is being received more positively, it's not really what I or anyone else was expecting, but it's fun.
Bottom-line: It goes in a different direction than the main game, and its experimentation with different directions you may either find appealing or not. If a 3.5-7 hour long stealth campaign with some cool creepy moments split into a two part campaign, and a 1-hour with additional new game+ content first-person arcade version of Evil Within sounds fun to you, then I'd say go for it. I found it enjoyable, not what I expected in either case, but I'm open-minded and found all three DLCs worth playing and fun, but enjoyed them for different reasons than I enjoyed the main game. But all the DLC together is around 6-10 hours of content, and a lot of it surprisingly doesn't feel recycled, there's a lot of new stuff, monsters, mechanics, and twists even to some re-used stuff, and I found it enjoyable, so I'd say worth it personally speaking, if the stealth campaign/first-person arcade sounds appealing and something you'd find fun.
