It Crowd's alright (I hate the laugh track naturally) and I also like The Life and Times of Tim; it was recently canceled, but is possibly to be taken up by comedy central.
I'm kind of surprised that people like It's Always Sunny in Philadelphia here. I honestly find it one of the least funny shows I've seen (I've sat through every episode), and DeVito pushed the series from immature and pointless to unbearable.
Most comedy shows seem to consist of such a bunch of goofish people bubbling around like idiots, expecting the audience to laugh at them simply because of their strange mannerisms or general stupidity. Apparently common consensus dictates that you don't actually need a lead role, plot, or target of empathy for the audience if you're writing a comedy sketch anymore. A'course I won't be happy until AD comes back from the dead.
