I just got through what I assume to be the entirety of Peter's symbiote phase, and I can't say it was too riviting. It really just goes through the motions without any real controversy; Peter gets the suit, initially appreciates the new power it gives him, then it goes to his head, his friends warn him that it might be dangerous and that he's changing for the worse, then he resents them for it, feeding his growing rage, it all comes to a head and he finally realizes he should be rid of it.
I guess considering the developers can't stray too far from the source material without losing the arc fans want to see I shouldn't be too surprised, but the way it's implemented within the game/story structure it just plays it far too safe. You'd think an unhinged Peter who's no longer interested in being the friendly neighborhood Spider-Man would result in some actual moments within the gameplay that emphasize this, but beyond louder, cracking punches and Peter talking scarier during combat you're really just doing the same thing you were already doing.
Instead of doing the regular missions and crime-stopping, but with more 'grrrr', it would've been interesting if the nature of your missions and the crimes got warped to reflect Peter's shift in morality. Instead of simply stopping a speeding vehicle, you'd grab it and chuck it into the river, for example. I was totally expecting Peter to maybe pay J.Jonah Jameson a visit and take him on a scare web swinging trip. That totally could've been a good mission, showing Peter indulging in something he might've imagined but never would've actually done, until now.
It's not willing to really cross the line with Peter and hurt the audience, so the whole arc just comes across as very cooky-cutter.
