Original UK title: "The Boat That Rocked". This is a pretty special film, that caters almost exclusively to 60s and 70s music fans and rebel-types. Basically, a combat between uptight, evil politicians and maverick, badass rock n' roll fans is depicted, with drugs, sex and alcohol being the prevalent themes throughout. It'll take you back to that crazy we're-changing-the-world 60s feeling, but in a decidedly british way, with some pretty decent humour in the background and some really fantastic acting all around. It has its share of badass moments, and is generally a film that you will take a lot from.
On the other hand, it's bloody long, and extremely caricaturistic. You could have switched the main bad guy for Darth Vader without much hurting the believability of the film. Also, in real life, radio pirates in the 60s were much more opportunistic and profiteering and morally grey than these guys, who are depicted as good-hearted but dirty badasses. And although the film is really long and has some dull moments, it somehow manages to contribute to the feeling of living with these people for months and months, and makes it that much more memorable if you can keep your focus.
In a sentence:
Extremely nostalgic, very well acted and good-hearted, but very long and unrealistic. It's a great feel-good film for 60s and 70s music fans.
