When I saw this show, I literally spewed my drink. If I could give it a half-star or a zero-star, I would gladly do so.
I am rather surprised that all the characters in the show aren't dead, since they have no pupils in their eyes. I can't fathom whether Grandpa Max has no eyes at all or is Asian. All the characters seem anorexic, and the colours are so darn blinding. The aliens are so complicated-looking, you can't even remember them. And everyone's faces are so angular, like square-shaped. Basically, the artwork is terrible. If you compare this to the original Ben 10, it's even worse. Gwen is either a boy or is simply mutated, and Kevin is definitely modelled after Frankenstein. As for Ben himself, one word: anorexic.
The characters are completely flat and are so obnoxious, you would want to reach through the TV screen and slap them. Everything is too extreme. Grandpa Max is too eccentric, Gwen is too naive and if I may say so, dumb, and Kevin is completely out of character. He is either overly macho or overly mushy. First episode- Kevin hugs Ben. Mind explosion. This is, of course, comparing to the previous one, which is so much better anyway. However, as a single show, the characters are still flat and shallow. Don't even get me started on Ben. In one episode, he just HAS to be so confident and he just HAS to say, "Me is awesomest hero EVER!" He is just so darn arrogant and shallow. And worse still, he never matures. No one does. There is a difference between CONFIDENCE and ARROGANCE, not to mention bleep-ness.
The voices are somehow really annoying as well. Also many things are off. Grandpa Max has a complete techno-lab with people working in it? Ben's Omnitrix looks all weird and recharges in five seconds? And who the bleeping bleep is that weird alien sidekick that speaks with a weird accent?
One word: Awful. Don't try watching it, seriously.
