It never ceases to amaze me how totally ignorant and juvenile some YouTube commenters are, that take the time to rant irrationally over certain movies. There's plenty of dumb-asses out there in internet-land, it seems.
This is why I try to find decent 'trailer' uploads for my thread that have their 'comments disabled', if possible. This function isn't used often enough for my liking, unfortunately, lol.
There are a couple of Chrome and Firefox addons that completely remove youtube comments from view.
@SilverWook: dunno if it's too relevant, but nearly every fullscreen movie I've found has a disclaimer on the back saying that it's been modified from its original version to be formatted to fit 'your screen' etc.
