Charlie Sheen puts on his tough guy face and then realizes he still has that Charlie Sheen face, so he runs with it. Here Topper Harley gets a little too close to the edge, in much hilarious fashion.
So the film's plot (while LOOSELY based off the real life Dan Black) is a pretty conventional "cop goes undercover and almost goes over the point of no return" but the manner in which its delivered makes for a pretty solid LOL time while adding in a lot of room for riffing. There's this juxtaposition between going dark and goofball humor that completely conflict with each other, making a weird tone to the entire experience.
This is all just backdrop for Chaz. Wow, what a terrible cast. Here's the thing. Everyone up until about 1995 saw Platoon and said, "I can do that. I just need to cast the weakest part of that movie." So this is just more of that, but it's hilarious. He's so bumbling in his lines and when he finally goes too close to edge and freaks out its about as good as you or I could do and we stink at acting, friend.
Next to his performance is the cast of characters surrounding Dan. Everyone's a little too nutty/inept to have made it to where they are in life. His love interest should be named Red Flag, his best friend tries to kill him for education, his nemesis is a kingpin of the drug industry and spends his free time robbing convenience stores for some Whatchamacallits and lives in a trailer and his government handler will let you spit in his face so meet the FBI Director. It's great!
Thus making it not stinker gold but 100% a good Sunday recommendation from us.
