Agreed, marajade... wintertime and the holidays is a really good time to release movies... People got to movies when it's cold out... He released this one about a week earlier than the LoTR movies... and I bet it'll pick up.
There's a lot of big movies out now... Narnia, the Potter movie... it's got competition for it's likely audience.
It'll be okay... Munich and Memoirs of a Geisha starts 12/23.
It may not beat Harry Potter or SW this year, but it'll do just fine.
