Some people are opinionated and aren't afraid to say what they think.
Although I do tend to see him post negatively on alot of videos which is odd when some of them are very high quality. Putting together a whole movie, and piecing it together to make it flow is alot harder than people think. Making movies, even ski ones isn't just putting the strongest skiers on the start and end of the movie, you have to create a flow, and a timeline that makes sense to viewers.
Alot of am movies and ones that people without a budget make are really entertaining because they're straight skiing and what most people on here want to see. After being on both sides of watching/editing like Eheath has I guess, he probably forms an opinion on it based on what he wants to see and knowing what goes into it?
For me I love ski movies but I've been watching them since I was 12, so for me I prefer a bit of dialogue and a bit of "material" or filler to ski films. I'll still be critical of them but at the end of the day I enjoy most of them even if they're to long or to much of one thing. Except Urban, I honestly think it all looks the same after 30 seconds of it. Unless it's an extremely unique feature.
