Ahem. I don't mean to offend, but my opinion varies greatly. Unless you're twelve, wear braces, watch CLAMP anime, and are a hopeless romantic then Twilight isn't for you. I was very interested in seeing it until I actually did. At one point, Edward is about to step into the sunlight to show a secret about himself. The movie builds up excitement and get's you ready for something big. So I watched eagerly, biting back the bad taste from the cheap acting. Instead, he begins to shine. Not brightly. Just shine.
Then, he explains that Vampires are irresistible, sexy, and smell great. Girls can't help but fall in love with vampires. And that's about how the whole movie goes. Talk about nausea. Seriously, the story was cliche romance, just made the male character also like the taste of blood.
So far, I haven't met a Twilight fan who was even remotely out of the aforementioned stereotype. So if you're expecting action, excitement, surprises, or even originality (putting fangs in a cliche romance doesn't count), then you'll be bitterly disappointed.
