It's fine. It's a typical big theatre. The only part I really dislike is the multiple escalator rides you have to take to get to the theatre. I'm afraid of heights, what can I say.
The entrance can get really congested because there aren't enough machines to buy tickets at.
Seats are fine, theatres are fine. It's really just a place to see a movie that can be relatively cheap on Tuesdays with a Scene card.
