I just watched the Howling II video and this guy is pretty funny. He put's a lot of effort in his review videos. (Probably more than the people who had the films he's reviewing actually did.)
That has become one of my favorites of his, first favorite probably Birdemic. The production quality of his earlier videos are vastly lower in quality than his most recent mainly because he's since grown his fanbase.
I think his movie reviews aren't as good as his gaming ones.
True, which is probably why I first started watching him, like for his Bubsy review.
My original favorite JonTron video was his review of Plug and Play games.
He then topped that with the Bootleg Disney games. Then I had the realization that the best material for Jon is bootleg stuff.
A big part of his humour comes from reacting to things so ridiculous it seems insane that they even exist. Bootleg stuff, especially from Asia, delivers just that.
I think his game reviews are better because he's got a better eye for flaws in video games. Gaming is clearly a big part of his life, especially considering he was once the co-star on Game Grumps and discussed game theory a lot.
