Spider-Man's been done, and this guy is not attractive in the least. It's going to flop.
My instinct is the same, but from what little I've read about he reboot, many fans of the Spider-Man comic books prefer Garfield as Peter Parker than the buffed up Tobey Maguire, because he's supposed to be an awkward, skinny nerd. (I thought Tobey
was a skinny nerd, but I guess he's too cool now.)
Garfield guest starred in Doctor Who a couple of seasons back, and at the time I thought he was good-looking (even with Ryan Carnes also guest starring), but in the pics I've seen of him lately, he's not doing it for me.
