This Saturday, Dec. 8, marks 27 years since ex-Beatle John Lennon was gunned down outside his New York City home. Fans of the singer — and he still has many — often mark this sad anniversary by playing his music, raising a glass to his memory, or lighting a candle in Strawberry Fields.

One thing fans will definitely NOT want to do is to see "Chapter 27," a film that takes the viewer into the mind of Mark David Chapman, the man who shot Lennon five times in the back after the singer had autographed an album cover for him.

This appalling film takes an excruciating 85 minutes to show us — guess what? — there were some pretty confused thoughts going through Chapman's head on the day he murdered Lennon. Hardly a surprise, but going through the details of Chapman's schizophrenia, the conflicting inner voices and delusion that he was Holden Caulfield (the narrator of "The Catcher In The Rye" by J.D. Salinger), is simply too much information.
