Auditorium 13 at AMC Center Valley 16

Sit like 1 to the left (H10) and you'll be dead center. The back row of this theater has a larger than normal aisle, so great if you want extra leg space but if you're used to leaning your foot against the back of the (unoccupied, I hope) seat in front of you, that's not really gonna work here unless you have super long legs.
