I don't frequent the Bloor Cinema outside festivals such as hot docs or Toronto After Dark too much, but each time I come here I'm always treated to a great atmosphere. Anyone that's been to a Midnight Madness screening at tiff would love it here (although it makes sense to say anyone that's been here would have fun at a tiff MM screening).
You know that you're going to watch a movie amongst other like minded fans resulting in a fun movie watching experience.
The actual building while old definitely has it's charm, but I highly doubt I would ever come in here to watch a recent movie I could watch at a better quality at a cineplex or amc location. But they do have a very reasonably priced concession stand with popcorn, pop and candy.
But they are undergoing renovations right now so hopefully they get a bit more oomph in their sound and picture quality and while seats are not uncomfortable maybe a little bit of new paint or something would definitely help.
Overall for the right movie this is a great venue but for the majority of the year this is not within my movie watching radar.
