Tosh.0 - Dear lord this show is unbearable. Two things completely ruin the show: One is that they're not doing anything new. The show is just a copy of America's Funniest Home Videos and The Soup, both of which are very funny shows (though AFV isn't as funny anymore). What they do isn't any different, so why should I care? But, I could forgive that problem if it weren't for the second problem: The host. Holy crap, Daniel Tosh sucks. It's just unbelievable at how unfunny, unlikable, rude, disgusting and douchey Daniel Tosh is. Every time he opens his mouth, he immediately ruins the joke of the clip that was shown. Normally, I'll laugh at the clip that was shown...and then Daniel Tosh talks, and I want to take my laugh back. How this guy got his own show is beyond me. The sooner this show gets cancelled, the better.
South Park - To clarify, I like South Park from Season 1 through Season 8. After that, the show is awful. The idea of "Let's see what's going on in the news right now and take it to it's most extreme" got really old after a few episodes. The fact that they keep doing it now for nearly every single episode just makes me want to bang my head against a wall. I really wouldn't mind it so much if they bothered to try some new formulas of episodes, but they don't. Every time, it's one of three episodes: Randy being a dumbass, Butters being a queer, or Cartman and Kyle continuing their "rivalry/secret love/whatever". It's the same thing, day in and day out. It really gives off a vibe like they're not even trying anymore. Like the creators say to themselves "We're so popular, that we can put out anything we want and people will love it!" And I really hate that lazy attitude.
Family Guy - ...I really don't feel like I need to explain myself on this one. The first three season of Family Guy were awesome. Every thing else after that sucks. I could probably go into an incredibly long explanation as to why Family Guy sucks now, but all it would do is just piss me off further. But, to keep things short, like South Park, the show gives off a feel like the creators think they're so awesome and cool, that they could put out the worst thing they could think of and people would watch it anyway. The show has drifted so far from where it started, that it feels like an entirely different unfunny show.
Workaholics/Two And A Half Men - Decided to group these together, because I hate them for the same reasons: Every character is an unlikable douchebag, so why should I care about what I'm watching? I see no reason to watch the show, if every character feels more like a James Bond villain than an actual human being.
Conan - I use to love Conan when he was on NBC. Now that he's on TBS, he's lost whatever it was that made him funny. I gave the show a month, watched it every night, and I hardly ever laughed. I took a break for a while, then watched it again a few weeks ago, and it was even worse. I never thought it was possible to sigh in frustration so many times in a five minute comedy sketch. This is not the same Conan 'O Brien that I enjoyed watching on NBC.
That's all I can think of at the moment.
