The comedy is excellent with little mini plots each week. It makes very easy watching and there are times when I must of watched 10 22 minute episodes in a day. On the other hand it can feel a little tame sometimes with the same characters doing the same sorts of jokes. For example George saying something silly which ruins his job or a relationship. You can't fault the quality and consistency though.
In terms of laughs, this is more of a chuckle program rather than one which will have you laughing uncontrollably. But every episode is crammed with entertainment. I can't think of a single bad episode or dull moment. The jokes just keep on flowing, even if they aren't always hilarious Kramer will pop up and do something weird and wacky. Larry David from Curb Your Enthusiasm is a producer/creator of the show and fans of his more recent series will love this.
My rating 5 stars out of 5.
For some reason I can't embed any of the Youtube clips for this show, so here is a clip from one of Jerry's live shows (which you get clips of in the sitcom episodes):
