Watch one of his vlogs then watch him público speaking. It gets clear that his filmmaking and editing skills are incredibly important for conveying this personality that you say people love.
After doing that. Think about what you just wrote and maybe reflect if you really understand the power of filmmaking and storytelling. Because it's like saying that you like Heath Ledger's Joker because of his personality and not all the screenwriting, soundtrack, directing, cinematography, art direction etc etc etc.
About proper grammar or language of cinema. It's always changing. Maybe someone said that after watching Orson Welle's F for Fake because he referred to the camera man and crew. Or to the first documentaries.
It's good to open your mind to what cinema is about.
Well, I`m a huge Metal Gear fan and what I can tell you is that they did an incredible job not only technically but storywise and also has captured the essence of an MGS game.
Congratulations to Hive! They`re awesome!
