I totally missed the Watchmen wave, but I did go see it opening night. Everyone else has said everything there is to be said about it, but I will still add that it amused me to no end that it was rated 13+ here in Quebec.
Keith went to see it at Cavendish Mall (read: Old Jewish people-mall) and said by the time you saw Doc Manhattan in all his...splendor, half the audience had walked out. Glorious.
