Part 1 was a little weak, but this is beyond disappointing. And I'm a comic book freak. I suppose if you hunger for a pretend Avengers 2 movie, you could give this a try for shits and giggles.
It's the same quality as the first (standard for a dvd movie but nothing special either in any regard) and the villain is......uninteresting beyond words. That and the characters are all pretty terrible here.
Seems Marvel can do live-action but have no idea how to do cartoon versions - the closest they came were the kid-oriented shows of the past (Fantastic Four, Iron Man, Silver Surfer, Spider-Man, and most of all, X-Men which is up there with Batman as the best superhero cartoon of all time). This is aimed at all-ages (as opposed to kids) but it fails to deliver anything of interest.
