Simply put, if you are a Twilight series fan, this is a must-see film...no questions asked. If you are not a fan or simply have not picked up the series, then my advice is to see the movie first, then read the series...that's how it happened for me. When I first saw the film (as a non-fan), it really was great, and it inspired me to read the series. I read through all four books in less than 2 weeks, and have now seen the film four times and re-read books 1 & 2 twice. Definitely worth your time.
