I recently watched the first season of Life on DVD and was pleasantly surprised by how good this show is. The show follows two LAPD detectives, Crews and Reese. Detective Crews is returning to the force after spending twelve years in jail for a homicide that he didn't commit. Detective Reese is also just returning to the force after a stint at rehab for a drug habit she picked up during undercover work.
The relationship between the two detectives makes this a must see. Crews is a quirky, fruit loving person who is trying to come to peace with his time in jail. His partner Reese is a sullen by the book person who is trying to not screw up her second chance.
A great part of the plot in season one revolves around Crews trying to find out who committed the crime he was accused and convicted of. Thrown in are some unusual cases to keep the detectives on their toes, which makes for a great show that everyone should check out.
