I don't watch everyone. I do follow quite a few regularly: Nostalgia Critic (but not Ask That Guy or Videogame Confesssion), Spoony, Linkara, LordKat, Pixels as Big as Cats, Litte Miss Gamer and Obscurus Lupa.
The others are hit and miss, here's a rundown of what I've seen:
Paw - Excellent Let's Play of King's Quest V, but his music coverage doesn't really interest me. He's got a nice style, and I really like that when he does countdowns, he doesn't use the same music snippet for every single freaking number on the countdown (like the NC and others tend to)
Still Gaming / Lee - Meh, I'll take him or leave him. Great enthusiasm, but his game coverage leaves little lasting impression. His Let's Plays are terrible.
Pixels As Big As Cats / Dena - I like her videos because she reminds me of an old friend and she chooses fun games to cover. Her Let's Play of Resident Evil was nice, but a little sparse on humor and snark at times.
Film Brain - desperately needs a writer. His delivery is good, but his material is not. He needs a wordsmith to help him with his opinions.
The Cinema Snob / Brad Jones - great delivery and humor, for most of his stuff, but he covers material I don't have any interest in or am outright repulsed by. Also, I find his "Big Box" and "Kung Tai Ted" videos boring.
Angry Joe - awful. His timing, his delivery and his writing all stink. I don't get why anyone watches him.
The Distressed Watcher - AAAAAGH! I started one video of his and I don't think I finished. He's a grating long-winded whiner who should shut up.
MarzGurl - bland.
JesuOtaku - Not bad. I enjoy her videos. Though, as with many other reviewers, she should probably do more takes to get things right and avoid major flubs. She should also avoid making points about things she doesn't know about. Either do your research, or don't make definitive statements. Do not do a whole episode critiquing a characters statements about science and technology if you don't know enough about the subject to be sure the character is certainly spouting nonsense.
Benzaie - Funny, when he's doing reviews and top lists, but his reporting and news videos are lacking in any real content or commentary. I hope he gets back to his Let's Play of Heavy Rain soon.
Jew Wario - hit and miss. Sometimes good, more often rambling and never getting around to any point.
Mike J TV / Shameful Sequels - pretty good reviews with mostly great jokes, but please stop with the creepy movie review schtick! All reviewers need to stop this trying to be pervvy or "secretly" psychotic or whatever joke references they're making to sleeping with relatives, drugging girls at bars or whatever. (at least during movie reviews). If you're going to be bashing a bad movie, you need to be the hero, or at least better than the movie you're trashing.
Good grief there are a lot of people making videos on that site. Even with comments on all the ones I remember watching videos from, I still don't think I've covered even half.
