Catherine Hardwicke's 2008 film adaptation of Twilight was the old buffystory of human falling for vampire. Not a particularly original storyline in and of itself. The movie was nothing special as it had no real shred of originality to it. Worse than that, they corrupt it by adding elements of teen drama, which is by far the worse type of drama out there.
Despite this, I do give Catherine the benefit of the doubt on some levels, as she tried her best to remain faithful to the novel. While I myself have never read the novel, I've talked to a few of my Twilight fangirl friends and they have said the film stays relatively close to the novel, minus a few scenes here and there.

I do have some major complaints about the casting though, especially and most of all, Edward Cullen being portrayed by Robert Pattinson. In the book, Edward's supposed to be the very definition of flawless male beauty, and they cast a guy that doesn't really fit the description, and his make-up doesn't help the illusion either. And I just have issues with Kristen Stewart as an actress (alhough I'm looking forward to her portrayal as Joan Jett in the runaways). She does a lot of films geared to children and young adults, and she really hasn't done well in any of them. I don't know, but I just find her to be a rather bland actress. I will admit the chemistry between Robert and Kristen on screen was actually quite decent. I haven't seen real chemistry between two actors like I saw between them in a long time, pretty well done.

The script was actually fairly solid. In doing well to remain faithful to the novel, a good script was born in the process. However, it's a shame that the script complimented a storyline I hated. The script may have been well written, but I still dislike it due to the story itself. Not an original, or even a good storyline. And it doesn't help that the characters are slightly cliche' and not really interesting in and of themselves.

The soundtrack was terrible. While I was happy to see Muse and Linkin Park in there, I was in trouble when when two songs from Paramore came into the picture. Along with my intense dislike for Paramore, there were a bunch of artists on the album that I didn't find terribly good at all. Soundtrack was not for me at all. Of course, when it comes to soundtracks, I am biased, as I loved the soundtacks for Queen of the Damned and The Scorpion King, because they were primarily hard rock and heavy metal.

The Bottom Line:
The film adaptation of Twilight is, in my opinion, one I could've done without seeing. While the movie had it's ups, the downs overweighed them. The script and the chemistry between the two leads being the only ups that come to mind. Other than that, it's all downs from there. It's not that I hated Twilight, it's just that when the movie was over, I had told myself "I've seen this before. Many times, and portrayed much better". I wasn't impressed by the movie at all, with a shauty casting job, a cliche story, and teenage drama elements to it, I am going to say, nonetheless, that Twilight is a one time rent.
