hahah i think people hate on the Lizard because......he's a man who mutated into a lizard? He's big, and scary and that's about it. Wow. IT's not like he's got any special magical powers, no special suit, not much of an originality etc. He's just another "experiment gone wrong" type of villain--which the last 2 movies have already dealt with. To tell you the truth, i don't like it when comics create animal versions of bad guys. Cuz then technically, you can create so many more lame-ass villains in that genre(The Lion, The Shark, The Bear, The Wolf). I mean, I feel for Doc Connors and all that (kinda like The Hulk) but there are faaaaarrr more complex villains than the Lizard.
And no lizard can regenerate perfect limbs as far as I know....tails in some species (geckos, anoles, skinks, etc) are as far as they go in terms of regeneration. Connors should've picked a friggin Starfish.
