If you like the Beatles, you will like this movie. If you aren't a fan, there is absolutely no point in watching it. There are no interesting characters, and there is no plot. There are, however, really interesting covers of Beatles songs. So, that is attractive.
It's like "The Science of Sleep" but with really no characters and more music. It's like "Moulin Rouge" but with no very great acting. There are thirty Beatles songs in it. People sing a lot. The same people sing song after song. But he's not Jake Gyllenhaal, and she's not Chloe Sevigny.
Some of it was amazing -- puppets, masks, special effects, beautiful. Some of it was very very clever -- "I Want You" and "Happiness is a Warm Gun" in particular. Some of it was, okay, schlocky: "Dear Prudence" and "All You Need Is Love." Okay, listen, I told you no one is going to win a reward for writing this or acting in it. However, it is very engaging. And I do love the Beatles. If you look at it as a very very long music video with regrettable interludes of talking and historically romantic layers, your expectations will be correct.
