The Spiderman games have a strange history. There's Spiderman 2, the all around best Spiderman sandbox game to date (that was released like, 1000 years ago..) due to its perfect web slinging and decent feel/flow, and then there were a few good games here and there, but never one as great as the former. And then of course, there's the terrible.
ASM2 isn't terrible, but it's far from great due to strange design choices. The most obvious flaw is its mission design choice. Side missions are around, but unlike Spiderman 2, you can't just drop in and swing out. This ruins the sense of fluidity, and this isn't really a nitpick, as it's -extremely- glaring. Every time you complete a mission, there's this long segment on the news showing your action. It gets old -very- fast. In addition, there's this menace/hero meter that serves to do nothing but make you feel like a tool. In Spiderman 2, you could feel like you're doing missions for self motivated reasons. It's strange how a game that is so dated can dominate new-gen Spiderman games consistently year after year. Pressing a button to dodge with Spidey-sense is nothing new; Spiderman 2 did this better by adding in certain combos that made you feel in control. ASM2 is just kind of a Batman Arkham Asylum genetically deformed copy that feels like a mess of clicks.
All in all, ASM2 isn't that bad; it does some things right. There are moments where you are swinging and it feels perfect; there are also certain missions where you feel powerful and skilled, and some story elements are interesting and actually entice you forward (somewhat). One of my favorite aspects of the game was its loyalty to the lore in terms of introducing some old foes that I hadn't seen in a while.
The problem, however, is that for every good thing there is a glaring flaw. Even webslinging, sadly, can turn into a mess really fast if you don't know what you're doing. You could 'make it' work, but the problem is, with Spiderman 2, it was intuitively effective. With ASM2 you actually need practice...I'm not sure how I feel about that.
