Well, there are a few I watch fairly regularly.
Nostalgia Chick. She has a different feel to the Critic, and can be pretty funny, too.
Linkara. Just about everything he has uploaded. I love his History of Power Rangers, and have watched most of them multiple times. He's also one of the best people on the site, in terms of quality. I have no interest in comics, and yet, he entertains me greatly. Partly because he favors the worst comics. Though, I find his view interesting. I had a great deal of respect for the points he made in the "One More Day" review. Yeah, he's probably my current favorite on the site.
Obscurus Lupa. I've watched a few of hers and I'll probably watch anything she uploads from now on. I kinda love how she actually seems to enjoy bad movies while also pointing out how bad they are.
JesuOtaku. Like Linkara, she has a great deal of respect for the medium she reviews. She also puts a lot of effort into her reviews and they tend to be rife with research and background information as well as a analysis of the work. She avoids spoilers, but all the same, I find her work enjoyable. Also, she has some strong crossovers, like with Sage.
Speaking of Benet the Sage, I've enjoyed a lot of his Anime Abandon episodes, too. So, I should include him on my list.
I'm also watching a lot of Filmbrain's Bad Movie beatdown and throughly enjoying it. I'll probably watch them all before long. In addition, I like the idea of Sci-Fi Guy, but he doesn't seem to upload much. I swear, not counting To Boldly Flee, he has appeared as a guest in more videos than he has uploading, in the last several months.
I've actually enjoyed most of the episodes that I have seen. Only real exception being Phelous. I watched his Aladdin review and found his style very annoying. Yes, I got that was part of the joke. It didn't make it any better.
Sadly, I never saw any of Spoony's stuff before he left. And he actually seemed to be a pretty good reviewer just from what I have seen of him in guest spots. I probably would have gotten to him eventually. Maybe I'll check out his stuff offsite sometime.
