See, the thing is that the only thing I DON'T hate about "Family Guy" is their undercurrent of comedy of the awkward/stretched-out joke. They don't usually use the device well but sometimes it is a device that can hit on accident.
Family Guy sucks because of the 95% of the jokes that are either badly lifted from other sources or are just "Hey, do you remember that? REMEMBERING IS FUNNY!"
What I like about Tim and Eric most of all is just how truly angry it is.
It is such an angry show. Our culture is littered with people aiming at the lowest common denominator and trying to sell them useless crap and not even doing it WELL and... everything about the Tim and Eric schtick is about just ratcheting past parodying those things and straight on into the grotesque.
A sitcom might send up these things as silly, a Saturday Night Live might send these things up as stupid... Tim and Eric send these things up as hellish horrors that are deserved by people lazy enough to not see through them.
And I just LOVE it. Your mileage may vary, of course.
Okay, let me try this nicer.
You could maybe see how someone would say "hey, they aren't even trying? Where are the jokes, why am I watching this?" But you have the right cultural milestones and a similar enough perspective to say, yeah, I dig this. I don't (i have never seen the show, I could like it I don't know) but I can't just say oh they are fuck*ng stupid look at their stupid name, trying to act cool, make the Bob Newheart Show again. Well I could, but that would be a dick move (you are making dick moves). So why do you want bands to make the same album over and over?
And one more thing: You ever try to name a band? Pretty much every fuck*ng name is taken. Even Kelvin and the Fahrenheits is a band for fucks sake. Anything you can come up with remotely clever or catchy that hasn't been taken you pretty much have to use. We wanted the be The Electric Blanket. There are already two bands with that name. We wanted to be the Grand Tetons, already taken, etc. etc.
