I disagree with most of the other reviews, in my opinion the acting is a bit cheesy. If I were a criminal I'd want these guys investigating me because they are mostly incompetent which would be fine if this were a comedy but it's not.
The story itself is interesting, and it is actually kind of funny.
As to the incompetence of these supposed police officers - the main character is knocking on doors looking for a woman. A guy answers the door and at same time the woman comes home, whereupon the guy at the door grabs a bat and starts chasing the cop and the woman. The cop and the woman split up, the guy with the bat continues after the woman... so what does the cop do, absolutely nothing and in fact looks unconcerned.
On top of that a lot of the character interactions are not all that believable. Possibly they are all escapees from a mental facility living out a dream
