The closest I can find is that he just seems like such a smug asshole.
Check out Tom Scott Plus! He challenges himself a lot on that channel and pushes himself out of his comfort zone! I think it’s a great display of his humility and shows him outside of his usual role as more of a narrator on his main channel.
Some of my favorites from the plus channel are the episodes where he gives his producer a tattoo, overcomes his fear of rollercoasters, and tries to learn wrestling.
It had some really rough moments intertwined with some really well done moments. Overall it’s fine. The shots of the cities and some of the fights were beautiful. I also really liked some of the zuko and iroh backstory that wasn’t in the original show. Some of the dialogue was very clunky and they mashed up a bunch of stories into the same episode which felt weird and didn’t totally work. I enjoyed watching it for the most part. It was never going to be as good as the original so I think going in with that expectation helped.
