Went to watch the Amazing Spider-Man a month after its release (I know, we're a bit late), it turns out to be uber filled on a Tuesday night, but we still managed to get tickets. I always enjoy going to the Forum than Cinema Banque Scotia because there's less people, and quieter. Above all, at Forum you can avoid those awkward encounters with your friends at the theatre.
The best part of Forum: the Coldstone in Timmy's. It's a good pre- or post-movie treat with your friends.
