I mean, that depends on your definition of genuinely being a fan....I've always watched and on some level liked his NC videos, but I've never found him very funny
On one hand, I do watch his content pretty much regularly and have for years now...but that's really just because I'm into nostalgic shit, and don't know of anyone who does what he does better than he does. That being said though, when I first discovered him I had the same opinions I do now, that he thinks he's way funnier than he is, and often his jokes range from poorly times/being dragged out too long or are just flat out unfunny to begin with.
So, I guess I'm a fan, but I still always thought he sucks on some level. If he were doing video game stuff I'd just consider him a poor man's AVGN, but since he's managed to tackle other things like 80s and 90s movies, cartoons, new movies, etc etc with the "angry review" method, I find I can deal with his often obnoxious attempts at jokes.
Like, I just watched his new commercials video not long ago, and I got enjoyment out of watching him muse in character over various commercials that I too remember, and some I forgot about or just never saw, but there were multiple parts where I knew the punchline before it even hit and knew it would drag on for too many seconds, and at those parts I roll my eyes and swiftly skip ahead.
