I'd like to give this location of Cineplex a 3-star review, but I go here too often to give it any less than 4-stars.
As other reviewers have noted ever since this movie theatre was bought by Cineplex, it's quality has gone downhill. It's not as clean, the food options aren't as good ...that's pretty much it actually. I've got no gripe with the staff as they seem to have taken the shift quite easily.
This location is fantastic as it's central for all my buddies coming from Brampton and those from Mississauga. It's also RIGHT off the 401, so getting to it is a breeze. There are a bunch of places to eat (mains, desserts, fast food, etc.) so the locals are great too.
The cleanliness is a serious flaw in Cineplex's master plan; when AMC ran the show, everything was spotless from the washrooms to the entrance to the theatres themselves. Now I'd give it a 6/10, it passes the sanity inspection, but it's like they're trying to just get by.
TL:DR: Fantastic location for a movie theater, with some questionable cleaning problems. Come to enjoy a movie, not the facilities.
