I'm not against the concept in general, it's a novelty and I can see the appeal. I don't want to denigrate the skill of the editing either, because...editing clips is hard, and doing it right is an art form.
I used to be a big fan of Youtube Poops a few years ago, which kind of operate on a similar premise. (Just in a visual way)
For this argument, I'm coming from a musician standpoint, and I prefer original creations. But, again, my taste isn't everyone else's, so I'm not trying to be judgemental. However, I enjoy musical discussions like this. I can always learn something new from other people
