There's a lot of hate on IMDb for this series, but you know, it's not all that bad. It's a standard buddy cop series, a little dim-witted humor, a bit of banter, "special" moments, shooting and fighting. It's nothing you haven't seen a million times before, but at the same time, it's nothing haven't seen done much worse before.
I think the problem people have is they're comparing it with the movies. Obviously this movie's attempt at Jackie Chan-style fight scenes is going to be pretty disappointing, but they do try, and I've seen worse fights on TV. And quite honestly, I never totally connected to Chris Tucker and kind of like the TV guy better. And while the series is quite inferior to the first movie, and somewhat inferior to the third, it's really no worse than the second.
This is not to say that I play to keep watching. I saw 3 episodes, and they were all okay, and if there wasn't much else to watch on TV I would watch more, but truthfully, even among mindless TV series, you can do better than Rush Hour.
But it's fine.
