I think that Henry looks awesome as Superman, however in the photo they've released, it looks like his hair's been greased back. I did see though that Henry's got a curl in his hair so perhaps it'll be different in the actual movie. Not that I'm that bothered about the hair, he still looks badass either way.
At first I thought the new Spidey costume looked wierd, however now I think it looks pretty cool. Plus I think Andrew Garfield will be awesome in the role.
The only problem I have with this film are the villains. While the Lizard is a pretty cool villain I guess, why on earth do we need Proto-Goblin? He's like the most obscure Spider-Man villain I've ever heard of.
Hopefully we'll have sequels where the villains get better.
