4TH PERIOD MURDER MYSTERY (2009)

Some films demand you just check logic at the door and enjoy the ride ... which is why I loved 4th Period Murder Mystery, a fast-paced thriller set in a high school in South Korea, about the smartest, most popular guy in class, Jeong-hun, who is framed for the murder of his biggest rival.  He finds the body along with a dowdy, true crime-obsessed classmate everyone calls Curtain (because she never pulls her long hair back from her face), who instead of reporting the death works with Jeong-hun to try and find the real killer in just forty minutes (the length of time for 4th period), before their fellow students come back to class.  From there the film sucks you in as clues are followed, chases happen around the school, and tension builds tight as a piano wire (sprinkled with perfect touches of comedy).  The murder itself is handled a bit lightly and a few burps in logic occur, but all is easily forgiven in favor of one funny, suspenseful, and outright fun rollercoaster ride of a film. (not rated)  A-
