There's a lot of good points in there, namely I remember reading that DC didn't really play ball with the press too much, sort of secretive and keeping to themselves. The other point about the click centric, "I don't like this so the whole movie's crap" is definitely true.
So many reviews for BvS, just read the headline, like The Film Stage in that video "BvS made 27.7 million on midnight, obviously a lot of you didn't read our review", click baity headlines and titles, reviews reduced to snarky sound bites, not bothering to see beneath the surface, it's either great or terrible (an that's not just the press).
Anyway, finishing up the video, thanks Jumpman, this is a good find.
And Matt, before you come in here and accuse me of anything, I'm not calling anyone a hater, or anything, it's cool that some people legit didn't like it, but there's a lot more at play here. It's all about perception.
