It would've helped with the hype, often find that during it, you can talk it up amongst your mates and it can seem a lot funnier.
But I still think it's a great show and stands out as a great from the past few years. Once you get the characters and they become familiar, I think you'll enjoy it more.
Have you checked out their stand-up/live version on which the show is based? I've seen the HBO special and it's pretty good, although you'll recognise a lot of material from the TV show or the other way around.
