MrBeast showing his real personality, a year ago.

I saw this a while ago so some of it could be misremembering. But he commonly does tit-for-tat advertising where the throws money around and has people fake praise him and call him a genius and say his ideas are great and his chocolate tastes good.

So he did a collab with this other creator, had already filmed the other guys video and assumed he would get his ad and praise. So he brings out his chocolate and has the guy taste his and compare to others. The guy is honest and says his chocolate is too sweet, to this, not enough that. He says hershey or something is better.

The guy's honest review in everything he does, his integrity, is more important than the tit-for-tat from one of the most powerful youtubers.

Jimmy's demeanor changes when he realizes he isn't getting his fake words and he cuts the guy off fast, glares at him, and moves on, and never worked with him again.

Two people are making a not at all candid video and OP believes Mr. Beast is being his true self rather than changing his personality for the camera. Despite knowing he's being filmed.

This isn't a defense of Mr. Beast, I don't like him

Mr whatever being an awkward, thin-skinned, and self-shilling asshat with a sociopathic, corpse-like, and mouth-only "smile" when he's not being given the praise he feels he deserves.

There is a lot of creative editing in the video. Whenever the guy makes a negative remark the video has a second panel zooms in awkwardly on Mr. Beasts face. It’s not even consistent sometime it’s the entire face most of the time it is part of his face it emphasizing whatever facial expression he’s having and making Mr. Beast seem sinister.

IMO it’s clickbait, cringy and not very convincing. The creative editing goes out of its way to make Mr. Beast seem sinister just because he is exhibiting a normal reaction. Everyone including Mr Beast is allowed to show negative emotions or surprised reactions when someone criticizes our work or something we believe in.

Part of being an adult is taking that negative feedback and reining in that negative emotion. Then using that criticism to improve and better understand yourself or your product. But it doesn’t mean those negative emotions aren’t there.
