I got alot of personal enjoyment out of this being a comic book "fan." There's lots to get out of it through just that, pointing when you see the thing you recognize from a book and whatnot but I'm willing to argue the actual story and content in it is worth it's 20 or so hours.

What isn't worth the 20 hours is the ultra-linear setpieces that break on you if you so much as inch your way out of the intended spot you were supposed to be in, causing the game to freak the fuck out and play 7 different voice lines from all the characters and you fall through the world. The game starts falling apart near the back-half and it really shows in those final areas and boss fights (In my experience).
It's a bit of a shame about the multiple lines part because the dialogue is actually a strong suit of the game. Not everyone can handle a game were people talk like people and that's fine they'll be weeded from the chaff.

The less said about the actual gameplay the better so I'll leave it at that
