I enjoyed this film a lot, though humour is an unpredictable thing and I know that it has not appealed to everyone. It's a spoof biopic of one Dewey Cox, a singer who goes through many phases in his chequered but largely successful career - various manifestations of Country and Western, a Bob Dylanesque protest phase, Love and Peace with the Beatles, some Punk Rock and so on. The makers have watched the excellent film of Johnny Cash's life, 'Walk the Line', and borrow shamelessly from it, to grotesque effect (for example, Cox is the surviving child of two brothers ; he cuts his brother neatly in half with a machete by accident ; 'The wrong kid died,' says Dad, almost every time he appears - he has even turned it into a little song by the end). There are many funny lines - it swings between genuine wit and grossness - and a couple of parody songs which made me laugh out loud (a protest song on behalf of midgets and a Bob Dylan song of mind-numbing and ludicrous meaninglessness). It is a hit-or-miss film, and some of the jokes miss by some way, but for me many more gave real pleasure. The film does go on by about 20 minutes too long. What is not in doubt, I think, is that the central performances by the very pretty Jenna Fischer as Darlene, the second love of Dewey's rollercoaster life and particularly by John C. Reilly as Dewey himself, doing all his own singing as he did in 'Chicago' and 'A Prairie Home Companion', Robert Altman's last film, are excellent and very enjoyable. So this is a film to approach when you're in a good mood and feeling indulgent, and then, I think, there's a good chance that it will give great fun.
