I'm not familiar with these characters, at all. Without knowing anything, the fact that it looks like there is a talking raccoon, makes me not want to like it. Ironman makes sense. I can say "Yeah, maybe..." at the Incredible Hulk. Spiderman, okay I'll buy it for two hours. Not sure about this one.
I wish they'd gone with the 1990s line up or a mix so at least it might be better known, plus if they tie to the avengers having Vance explain why he had Captain America's shield could have been entertaining. They actually put that raccoon in Marvel Vs Capcom 3 and got so much heat for it.
