Having never read the books, I've surprisingly enjoyed this film. As a non fan having no idea why there is so much hype, but can understand its appeal. It's like a modern revamp of classic love storys like Romeo and Juliet or Jane Eyre with a mix of completely reimagined vampires. While this won't have same impact as other vampire fiction like Dracula, Anne Rice's Vampire Chronicles but it know how to appeal to it's audience.
Pros
Very modern indie style directing, good sense of humor, great mix of romance and danger, leaves you wanting more when it ends
Cons
Acting isn't anything special, Kristen Stewart is very talented and nice to look at but she hasn't been given much to do (until the climax) despite being in 99% of the film and Robert Pattinson is just dull, vampires seem more like blood-sucking wingless fairies.

The Twilight series has its fans (predominantly teenage girls) and its critics (guys) but i can honestly say as a guy that it was quite good. Bella played by Kristen Stewart is an agst driven teenage girl who has moved to Seattle to live with her father but soon falls in love with a weird guy called Edward (Robert Pattinson) who happens to be a vampire. Now it is a love story in truth but i dont find it too cheesey and can actually enjoy the story. There is an action packed scene near the end which wets the appetite for future movies. Enjoy

The book is very good, I'm not denying that, its the best one (the book) but I didn't like the film, it was slow, and Robert Pattinson doesn't even really talk in the movie, no action and pretty boring.
