My go to theatre when I want to see the new blockbuster movie on a giant screen in Ultra-whatever possibly IMAXy 3D-ified glory...unless it's not playing here. For some reason they seem to occasionally trade off current movies with Yonge and Dundas square. Weird. Anyways, it's a nice theatre, but it can be pricey so be sure to use your SCENE points for the expensive tickets (they work the same for a 20 dollar ticket as an 8 dollar ticket so save them). Nice seating and huge theatres.
Also, they have one of the Coke Freestyle choose-from-a-giant-list-of-pop pop machines and a bar, so plenty of drink options.
This theatre will also occasionally have opening night promotions and things (check online) and I've gotten a couple cool posters seeing movies opening night. The one time I did have an issue at a movie (movie stopped 15 minutes in and then restarted after 20 minutes) they made up for it by giving us each 2 free vouchers.
Some nice bars in the area for post-movie debating and arguing too...
