During the show's original run, and the period in between its cancellation and revival, I loved it. Thought it was the funniest thing on TV. However, when the show came back, it just didn't seem the same. There were still some funny gags, and a few solidly enjoyable episodes here and there (like "PTV"), but overall it was less funny, more crude and self-indulgent, and the characters just weren't as likable as they used to be. Plus the show's formula just became tiresome after a while. I stopped watching regularly after about season 5, and on the occasions where I catch it, I might be mildly entertained for a while but ultimately find it to be empty. And although I still find the classic season 1-3 episodes to be more funny and charming than the later ones, I've realized that even they don't approach the creativity of The Simpsons and South Park at their best, or some of the really good sitcoms I've gotten into since then like Arrested Development and Community.
