I'm glad i'm not the only one... I didn't spot him either! No Stan Lee in a Marvel movie??? Now that's just plain wrong!
As for the movie - well it's not that bad... I think people have to remember it's based on a comic book, so a bit of 'leaving your brain at home' and suspending belief is required.
All in all, thought cage was good, young cage was very good, sfx were not bad (could have been better) and the bad guy fights could have been a tad more impressive... would have liked to seen a bit of a face of between GR and Mephisto - but that may be kept for the sequel.
