Who cares about Tamara Drewe? I don't...
The biggest single mistake was to centre the movie around a character it was so hard to care about. Tamara wasn't likeable, but she wasn't a real villain either. She wasn't funny, she wasn't sweet, she wasn't particularly cruel - she was simply insignificant.
If you can't elicit some sort of response for your eponymous role, the film is probably going to be a howler no matter how good the rest of the cast is - and I thought they were decent enough.
