In all seriousness. While I have seen some bad behavior by adults at movies, I would suggest its been far from epidemic in my experience.
As for children; granted, I have none, and so rarely attend films that would appeal to them................what was that whole Frozen thing anyway.......
If you just to stick to movies that would play TIFF.........should keep the squawking pre-teens to a minimum. LOL
I see the odd brain candy, like anyone; but I just don't see it opening weekend, in the evening..........which again tends to resolve a lot.

I started going to movies regularly w/my folks when I was 9 and on my own at 10.
If you have kids or friends/family w/same encourage them to take their kids, and to teach them courtesy, then let them go on their own.
Its not only among the most accessible art forms, but a great socializer when done right.
Extra thought, make sure to take the kids to something with a subtitle..........tends to have a different vibe that encourages self-policing more.
