It goes without saying that sitcoms in the 80's and 90's were better than the ones today, but this was a show that was way before its time and probably would still work in today's edgy, controversial society.
You can see similarities between this and Seinfeld: the stars behave in a very close fashion and the supporting characters are complete baffoons. You'll be hard-pressed to find a show as funny as Seinfeld (because it does not exist) but this one comes pretty close.
Garry Shandling seems like an all-star here, just spitting great one liners after another. Excellent start to a great series.
