I finally sprung for the membership to this theatre since I've been here so many times. As soon as I do that, the cosmic forces of the universe bring shitty movies to the theatre so I didn't even use my pass for 2 months. Despite this, I still love the beaches cinema (i refuse to acknowledge the singular form of "the beaches")! The membership gets you a buck off the regular price ticket (can't use on cheap nights) and free parking in that lot on Eastern.
The theatres aren't monster-size. The seats are comfortable and at a good slope so even if a person of high stature sits in front of a vertically-challenged person like myself, you can still see the screen. It's clean and the floors aren't incredibly sticky like other theatres so you don't feel like you're going to leave the sole from your shoe behind.
You know what's a heavenly night? A burger from Burger's Priest then a good movie here with popcorn (yes, there's always room for popcorn!).
