I just watched 4 of his videos (including the one you posted)
Doesn't seem like the sort of person I like - He's got a real bee in his bonnet against actual critics, and one video is just slagging off Brie Larson for 7 minutes because she launched a Youtube Channel.
Tbf, he's on the money with Brie Larson
He can be a bit abrasive and it's only in recent months he's been hitting hard at critics, that's mainly because they're jumping hard on any relevant bandwagon. However the same can be said of just about all people in social media space at the moment.
He came to my attention with his 'The Predator' video, I think anyone would be hard pressed to say he was wrong in what he says here.
I will say there are plenty of his videos I don't agree with as sometimes, i think he goes on a tirade for a little controversy and reaction but overall, I find myself agreeing with much he says, especially when it comes to the recent star wars movies.
