The tiger was computer, yeah. But great - vivid, lustrous..... real.
It's in 3-D. And Lee has the full palette of modern digital cinema to use and he more or less goes balls out. It's kind of a symphony to the state of the art in digital cinema.
A little too much god-bothering for my liking, but once you accept that what you're watching story-wise is a whisper-thin allegory, you can just lean back and enjoy a master at work.
The first 100 pages of the novel are about god, he only mentions the tiger once. Okay if it's 3-D I'll give it another chance since 3-D generally looks shite in 2-D.
