The brow is certainly not very pronounced like it is in the comics. They definitely seemed to go for the Chiklis type of look with the face. My two main problems are the no pants, that's going to look stupid, and the CGI isn't very good. This would probably be adequate 10 years ago, but compared to some other effects drivin movies it doesn't really hold up. They've got the blue eyes, but it looks weird. Can't put my finger on it.
They definitely improved on the effects from the first teaser (you can notice this the most with Johnny), so clearly they're still doing work, but they aren't spending much on this film, so I'm not expecting much.
