"Twilight" is a popular fantasy romance by Catherine Hardwicke.
The extreme hype of the movie franchise, and the novels, somehow seemed to take overhand. Due to its success, there were many critics calling it the worst movie of all time, and others which called it the best.
Looking critically at it, "Twilight" is neither. It is not terribly bad, but still, it is not exactly good. The plot is not even that uninteresting, if you keep in mind that this was the first movie that depicted vampires as "the good ones". It played with the image that a vampire had, tried to create something new - and did so. Unfortunately, the adaption is rather negative. The romance between Bella and Edward seems a bit underwhelming, there are no big emotions like in "Titanic" or "Gone with the Wind". At some parts, the movie can be a bit silly, especially the baseball scene takes a lot of the athmosphere.
Also, the Twilight universe seems less thoughtful and consequent compared to other epic sagas such as "Harry Potter", "Star Wars" or "Lord of the Rings". It does not have the complexity that these franchises have.
The cast is not well-chosen, having a stiff, uninspired performance by Kristen Stewart, who seems more tired than anything else.
On the plus side, it is a better movie than most other blockbusters that come out nowadays, not having non-stop action and still something being diverting.
Also, the soundtrack by Carter Burwell (who did the overwhelming scoring in the Coen brothers' "Fargo") is excellent, being the highlight of this movie.
"Twilight" is not the worst movie of all time, but still has some fatal decisions made. If they would have chosen a better cast, and added more emotion to it, it could have been done much better. But the way it is, it simply is disappointing. --------------------------------
(SPOILERS may follow:)
There is actually only one scene keeping this movie from a PG rating:
a vampire traps Bella, throws her against a column, and then violently breaks her leg by punching against it (though not detailed, it is violent). Then she is bitten. However, she does not become a vampire when Edward saves her. The evil vampire is then killed off-screen by having his limbs removed. It is off-screen, this could have passed in a PG movie.
(END OF SPOILERS)
This is a light PG-13, one bordering on a PG rating.
But for those who are under 10, caution is recommended.
