I think people go to the word "crap" as a descriptor for games they don't like way too quickly. To the point where the word loses its impact.
I've played truly crap games. Tomb Raider: Angel of Darkness. Legacy of Kain 2: Blood Omen. Batman Beyond. Superman 64. Those games are truly failures of game design in every way, from visuals, to controls, to story, to level design.
I'm not a fan of Activision by a long shot, as I've said many times before, but ASM2 is not a "crap" game by any reasonable metric. When it comes to how I evaluate games, I look at things like controls, game/level design, visuals, audio, story. A game isn't just one of those elements, but all of those elements combined. One of my favorite games of all time has pretty iffy controls (Shadow of the Colossus), but excels at everything else to the point where that doesn't matter.
I played ASM2 for a few more hours today (from about 7:30 to 10:30), and it isn't a crap game in my opinion.
Graphically, the game is low bar for this current generation. Its a cross gen title, but other cross gen titles, that have infinitely more scope than ASM2 are better in the visuals department, like Assassin's Creed IV.
Control wise, the game controls as well as any other third person action game not developed by a console first party. That is to say, it's not as smooth and responsive as a God of War, but Spider-Man does what you intend for him to do the vast majority of the time. The camera is the real problem here, especially in combat situations. Moving around the city is fine, but in combat, it can be problematic by not being where it needs to be for optimum fighting. Swinging around is surprisingly satisfying, and loads better than the previous title, even if it doesn't have that SM2 physics.
Game design: it's a by the numbers open world and Spider-Man game. Nothing ground-breaking here. Roam around, complete side missions, find collectibles, do story missions. Variety is lacking in this area, which is a problem, but what's there is enjoyable enough. I feel it suffers from the same thing inFAMOUS: Second Son did, in that the side stuff just isn't compelling. It's busy work to pad the length of the game. The game loop in ASM2 is fine, it's not a broken loop, it's just limited and needs diversity (much like Second Son).
Sound: The musical score is ok, but the voice acting is pretty bad. I'm sure a lot of that has to do with the mediocre script and voice direction, but it's just not very good. Line delivery is often over the top, or not emphasized enough. "CK" and Aunt May stand out the most as being pretty terrible. Peter/Spider-Man is alright, but inconsistent.
The game is slightly above average, but not by much. Hardly crap. That should be reserved for games that are truly bad and badly designed. There is some enjoyment to be had if you are a Spider-Man fan. Non-Spider-Man fans should stay away, there's just nothing here for you.
tl;dr: If you're going to call something "crap," please at least explain why you think it's crap. The same applies to something you fine "awesome." I don't find one word, one off criticisms very helpful.
EDIT:
I was at Activision in 2005/2006. They used SM2 to train testers. I only stayed in the dungeon for a couple days, though: I was soon assigned to the Quake 4 PC team.
Haha. Same, got put on X-Men Legends.
Lol! Small QA world. After Spider-Man 2, I moved on to X-Men Legends night shift, and was on a few more projects before I was finally let go (Doom 3, The Movies, I was the localization Floor Lead for the Gamecube version of Lemony Snicket's A Series of Unfortunate Events), Madagascar, Quake 4, etc, etc. I've worked on a bunch of titles at ATVI. I can't say I look back at that time fondly. The best place I ever worked for not counting my current gig at Capcom was Obsidian. Those guys were awesome, and I miss working with them. Fun environment, and Feargus and Chris Avellone were great people to chat with.
