I must say that even though i had absolutely no hope for this show, it really surprised me. it wasn't perfect, but i can say it was good.
Hulk- Hulk is really good in this show, instead of showing him as a angry guy who just happens to be on the avengers and gets mind controlled all the time, the actually portray him as a Hero, not a Monster, which is always good. He has the light Humor thing going on, but it still feels like hulk, and while it's not EMH's Version, it's close, which is good enough. Oh the voice is as always perfect, and it's nice that they are going with the Gravage Hulk
Jennifer- Great Voice and she has the sassy fun personality she is usually known for, so a plus for you.
Red hulk- While i think his voice is perfect he is kinda the Black sheep of the team, acting all tough and snobbish, which is understandable and they do manage to balance that, and i like the army mixture to the design. I just hope the don't go over board with teh Douche Bag thing.
A-Bomb- Seth Green? Yes please. seriously, i think seth is perfect for rick jones, he surves as hulks conscious and comic relief, plus he's got that fun serious type personality rick is known for. Besides, the voice is just perfect.
Skaar- Ohhh i had my skepticism on this one because it felt that he was now the savage hulk, and while i'm fine with him being the loose canon, that doesn't mean he should be hulk Jr. but at the end of Episode 2 you'll see that skaar isn't as stupid as he claims to be, in fact i loved the ending.
The Plot is simple and easy to follow, which isn't exactly a bad thing, considering that Avengers assemble has 3 plots per episode and USM doesn't have a plot , it\s just random action, which sucks. and There are some elements that makes you excited for what is going to come next. Plus Leader is here is that has me sold
The action wasn't as good though, it feels clanky and sometimes weird, but over all it isn't to bad, i mean at least the designs are cool and characters don't bend in unnatural ways.
for once, i am excited to see the future episodes, and while it's not perfect, it's at least promising.
