Based on Yann Martel’s beautiful little book about a young man and the sea and a tiger, this film transforms into a big, imposing and often lovely 3-D experience. Ang Lee directs and while not all of it works, there is a lot to admire. Pi sets sail with his family on a freighter, accompanying a slew of zoo creatures. Terrible weather. The ship sinks. All die except for Pi, a zebra, a hyena, an orangutan and a Bengal Tiger named Richard Parker. The adventures and astonishments keep on coming.
