As long as you realize that about half (or more) of what you see in this film is NOT true and it's a completely ridiculous and insane version of a real life celebrity's life, then by all means watch and enjoy it. It is NOT good history, as practically no one believes Chuck Barris' nutty 'autobiography' (in which he claims to have been a CIA assassin) and the writer and director of the film took no efforts to portray the rest of his life accurately. Despite the ever-present love interest in his life, Penny (Drew Barrymore), Barris never was married to a Penny...but had three other wives. And, often even the sequence of his TV shows isn't even close to being right, as the film shows him, while hosting "The Gong Show" (in the late 1970s) talking about another show he was thinking about making, "Operation Entertainment"...even though this show aired about a decade earlier! So don't see it as any sort of lesson about Barris...none. If you can do that, the acting is quite nice (with a lot of high-profile actors making bit and larger appearances in the film) and the insane script is pretty interesting....at least until the very maudlin and dull ending.
