The show wasn't amazing, but it definitely was getting better by the week.
HBO could, and did, do worse for a summer comedy show. I think this sums it up pretty well:

Shocking.

Meh, while not the greatest thing on TV it was still better than a lot of the rubbish that continues to stick around year after year.

Good riddance!

Not at all a surprise... the episodes always seemed really short and not terribly funny.

I'm neither sad nor happy about this. I grew to enjoy the show as well, but it wasn't as good as it could have been given the talents involved.

It was pretty decent, could not have been costing HBO much to make, so slightly surprised, but not shocked.

I was going to write the exact same thing.

I dropped it after 3 episodes.

I could not imagine paying a premium channel to watch a bad Fox-quality sitcom with swear words.

poor jimmy, he may never learn what to do with his hands now!

I wanted to like Lucky Louie, really I did. But if I wanted another serving of "Fatguy & Hotwife" I'd be watching network TV.

It was OK. Had some moments, but was nothing spectacular. It was a nice diversion for the summer programming, though.

It did get better as it went along and I thought sometimes it could be really funny, but I'm not too shocked it got axed...however, with it's extremely "play" like feel and low budget sets, how much could this show have cost to produce? It must have really done poorly not to get another season from the network that gave us Arli$$

i thought it had funny moments, i would have liked to see a second season.

they definitely should have done away with the studio audience, they hardly laughed and really brought down the show. granted it wasnt a hysterical show, but the audience laughs were pretty nonexistant, and nothing you should have broadcasted.

I watched an episode and a half an couldn't take it anymore. Not funny. Which is kind of a killer in the comedy field.

Enjoyed this show, thought it was pretty funny... especially after the first few episodes. Acting was crappy but show was fun.

You lasted approximately 87 minutes longer than I did.

The production values were way overbudget, and there was just too much hate on the show.

It was growing on me

I tried to like it, but I just couldn't. It was too stupid and negative.

That anger was perfect for people living in such poverty.

I'm very surprised HBO didn't renew it. Aside from Larry Sanders and Curb Your Enthusiasm I found this to be the best HBO comedy series I've seen in quite awhile.

If the creators sold it as a per ep download purchuse I'd buy new ones.

Classic line!

Although I found this show to be much better than any fat guy/hot wife show I've seen on broadcast.

You mean 60. I rarely saw an episode that seemed to be more than 20 minutes long.

I am honestly surprised it made it all the way through one season. Let alone managed to get to two.

Oh I wonder what they will do with that bland set?
