As one of the largest movie theatres in Brampton, this is an exceedingly busy location. As such, a certain amount of disarray can, and should, be expected. I've been to this theatre many times, and although it's not my preferred, it will do.
The staff do their best to keep the lines moving, the bathrooms clean, etc, however, there's just far too many customers versus employees.
They have the 3-D and AVX theatres where you can choose your seats in advance, as well as the free style Coke machines, though it can take quite a bit of time as many people don't seem to understand how they work.
As they are almost always packed with crowds, I would recommend doing the online pre-order tickets that you pick up via the machines. This location would benefit from adding a few more kiosks as the main queue line is very, very long.
