Is Twilight the worst vampire movie ever?

Yes. It takes everything that makes the genre interesting and removes it while simultaneously taking everything revolting about the genre and magnifying it to ridiculous levels.

Twilight is one of the worst. Stephenie Meyer did absolutely no research when she wrote this book. She took out vital aspects of vampires and made no effort to try and sustain some of the important qualities in which vampires carry. She made cool and interesting creatures like vampires and made them look like wussies. Twilight not the best, but not the worst.

Definitely not the worst, Queen of the Damned, Female Vampires and Blade: Trinity are better (or worst) contenders.
