The Good Guys. I absolutely loved that show. The final episode's a bit of a downer as they tried too hard to go with a big finale, but overall, it's pretty damn fun Also too bad they're not gonna make a second season of it.
The concept's pretty basic: Loose canon cop teams up with all-by-the-book cop. The entire setting, though, the crimes themselves, and just about everything's so masterfully ridiculous that it's simply fun to watch
