Quandary

I am reading the Girl With The Dragon Tattoo. I'm not too far into it yet, the protagonist is just about to start his investigation into the missing woman. All the characters have finally been introduced to the reader but not all to each other. The movie opens here this weekend! It's not the U.S. Version, it's the original and probably will turn out to be the better of the two. I'm kind of guessing though, it won't stay here very long. therefore, if i want to see the movie on the big screen, i kind of have to see it this weekend or maybe next weekend if i take the chance that it's still here. The problem with that is it will spoil the ending because the book is always better, isn't it? No spoilers, please but if you have read the book and especially have seen the movie as well (it's been out in the UK already), Should i see the movie before i finish the book? You know books are always better and it often spoils the movie so maybe it's better to see the movie, spoil the ending and finish the book after. Aggh!
