A good-humoured and moving British comedy as a tribute to pop-rock7/10
If you think of "Four weddings and a Funeral" or "Notting Hill", you will be a little disappointed, being here the overall tone not so brilliant, dialogues not so sparkling, however, the both humorous and moving atmosphere of Richard Curtis's comedies is still recognizable.
I think the real protagonist in "The boat that rocked" is music, that sound pop-rock that in the 60's began to move the world, and to be opposed by the establishment as a dangerous weapon in the hands of the multitudes, as a threat to a well consolidated but no longer valid system. Among unreal situations, a totally-lacking plot, among odd and eccentric characters, what only matters is that power of music to revive one's spirits, to give voice to the most uncontrolled, animal, ancestral instincts of man. And thus becomes, in my opinion, the most vivid scene that of those hundreds of records floating on the water, the symbol of a generation, of an era that was then ready to explode, and that no strict establishment could have wiped away, even once illegal radio stations were shut down.
No revolutionary message is conveyed: it's a good-humoured and at intervals melancholic tribute to a generation who, maybe ingenuously, but deeply, and truly believed in out of time-values, friendship, respect, love, and believed that music was a strong, and powerfully effective means to convey them. Even if you don't belong to that generation, each of us has experienced, one or more times in one's life, the communion of a piece of music with the most sensitive chords of our soul: it's about something emotional, but also physical and that's what the director just wants to celebrate.
If you are fond of music, or simply you have once in your life been moved by a song, you will like this movie, or at least enjoy it for what it is, without the necessity of too much criticism.
