Watched Wolverine, and aside from the design of Wolverine himself, I kind of dug it.
Wolverine is too slender, tall, young-looking, and hairless. I also don't like his voice. That scene early when he was helping his friend on the roof top, and you heard his voice as the camera showed him from his feet and panned up, I could've sworn it was gonna be Gambit. Need a gruffier voice than Peter Petrelli.
Most curious thing about these Marvel anime is whether or not they can have other big Marvel characters crossover. But so far, I like what I see.
