I'll tell you what's NOT good along these lines:
"Paul McCartney Really Is Dead - the Last Testament of George Harrison"
I'm a big Beatles fan, and I went a few weeks ago to an "Abbey Road on the River" festival in D.C. They did a screening of the film there, and talk about unintentionally funny. The conceit of the "documentary" is that some no-name studio receives a recording in the mail that claims to be the voice of George Harrison explaining that Paul really did die in a car accident, and that they covered it up because British intelligence agents said it would cause a rash of suicides if Beatlemaniacs learned the cute one was dead. They replace Paul with "Faul" - a fake Paul McCartney. It gets more and more absurd, including a line from "Harrison" that suggests a cop on the scene of the crash looked at Paul's disfigured dead face and said "Doesn't he look like a walrus?" TERRIBLE.
