Those are Fragmovies.
I myself enjoy looking at them, because they usually have relaxing songs which match well with the kills. They are pretty much highlights of few games.
There is different style of videos: frags, jumping, funny videos, tutorials.. and more, let's be honest, people watching those videos are DP related and they know " How good you are " which is why they are watching it ( talking about fragmovies ).
Why'd you think that it's a lame way of presenting your skill if you actually spend time on doing something enjoyable to watch for most of the people ? The way you present it: " The main protagonist never dies and kills everything" , " Very predictable " , "Very Boring", "Everyone can cut his video in a way to look as the biggest king of the hill " it just sounds like you are full of hatred with jealousy.
The only thing that bother me on fragmovies is the " selfish side ", and im pretty sure it is what you are talking about without really saying it. I might be wrong but that's how i see it.
I made few videos, mostly fragmovies and i'll explain you quickly on why i did it and why i would do it if i was playing the game still if it can help you understanding it. I had tons of demos, and playing the game for so long, i wanted to do something so that all the time spent and my demos are not a complete waste and lost. So after doing it, i felt like having a least of a reward for playing the game.
Thats understandable to hate something, but i don't think doing hateful criticism will lead anywhere.
