Thomas and Friends.I used to love the show back when it was better quality than it is now. I'm lucky Season 17 is as good as it is. A marginal amount of stuff from the fanbase is OK, but 80-90% of it is absolutely crappy. Kinda sad, really.
It's this right here for me, but when I run into a raging swaggerific xbox MLG wannabe is when I want to rip my eardrums out. It's mostly why I left the COD scene. The COD series ended with COD4 IMO, COD4 had the best community above all other COD games.
This man/woman knows what they are talking about. I am by far not a COD fan, but if I was, I would say something along the lines of "OMG gohsts wuz so much betr than cod4, cod4 had ten less polegons per player modle" The whole series should stop now, while it still has a chance to stay profitable. No self-respecting gamer would buy the next COD game just because it's COD. Unless they bring Soap back from the dead, COD is done.
After E3, I'm not a big fan of the SSB fandom. A good majority are people who know nothing. Others seem to just hate because no special techniques from Melee. And then there are those who just say "play the game that the developers gave you." Which I consider to be a terrible idea, since developers aren't perfect. Mods are awesome for Brawl.
Sonic-Amy Amy-Shadow Fan bases. Although I have to admit, 5% of the Fanfics are worth it, they have bad spelling, and are based on Sonic being a Jerk to Amy, and then Shadow swooping in to save her. It was good the first time, but Terrible the 5,000,000 times it was repeated.
The fandoms that spend paragraphs dissecting and ranting about a one line post.
Worst fandom, not really a fandom, but a group of cocksuckers and trolls. I call them losers. People who feel the need to criticize everything they don't like or believe is stupid or wrong/gay. Too many of them on the internet, they make up like a 3rd of the population! They just step on everybody's feelings, work, and forum pages. Go to hell "Losers"...
