Though the setting and the story are different, this sitcom is very much like its parent series (One on One) in terms of laugh count and quality. Both shows are far from great, but better than the average show of this type (light comedy aimed at urban and African-American audiences). There are some good laughs in every episode (though they could use more), and the plots aren't entirely predictable.
The show is also a bit more ambitious than most of the shows you'll see it compared to, because the cast and setting aren't entirely African-American. On the debit side, the two main characters are the most boring. I'm much more interested in Walt, Ace, and Candy than I am with Kevin and Tiffany, but the same can't be said for the writers (so far). I think at least part of the blame for that has to rest with the actors--Marques Houston is prone to over-reliance on cheap laughs from urban/hip-hop clichés, while Shannon Elizabeth's character is a walking, talking stereotype.
My advice (assuming the show lasts) is to use the other characters more, and get out of the shop more. I'd especially like to see more of the neighborhood.
