"A Low Down Dirty Shame" is a Wayans brothers film, which means it could go either way from being hilarious and awesome, or like something you'd find in the $1.99 DVD section of a 7-11. This one stars Keenen Ivory Wayans, who was the host of the sketch comedy show, In Living Color. Alongside him is Jada Pinkett Smith. While I enjoy Jada PInkett Smith's acting on most occasions, it's not enough to make this movie anywhere near watchable.
The movie is about a detective, played by Keenan Ivory Wayans. It is also directed, written, and produced by Keenan Ivory Wayans. That's a tough thing to do - write, direct, and act in your own movie. That means there's no one there to tell you that what you're writing isn't funny, or what you're doing isn't funny. That makes sense of why none of this movie is very funny.
