I really like this guy. He does three series, Gaming Mysteries, Obscure Gaming and Bullshit Creepypasta Storytime. If you haven't seen him I highly recommend you check him out.
Emer Prevost (another YouTuber I enjoy watching) talked about Mr. Enter in one of his recent live streams and addresses the problems with him. I agree with a lot of points made here.
I don't get upset over people disliking Enter. If you simply dislike him that's fine, It's just the fact that people downright hate him. This one guy I came across named Clay Claymore makes pretty much nothing but commentaries about how much he hates Enter. And I'm like, if you hate the guy why do keep watching him?
Over the year I've seen Mr. Enter get a ton of hate by people. Commentaries, blogs dedicated to hating the guy, etc. I know his reviews have flaws but I still enjoy watching them and hearing his opinions.
None. If any of the characters in the show die, the parents of the children who watch the show are probably gonna start bitching about it and will be like the whole "Last Roundup" situation and the animators will have to re-edit and re-write the episode.
