There are so many vampire films out there, and so many following the same tedious plots and themes, that the real pleasure for me in this one is that it did something different. Essentially, two women find themselves with superhuman abilities and a thirst for blood, but there's no loss of soul, they're not suddenly evil or mindless. Their subsequent development is determined by their original human personality.
The two main characters are lesbians, but for the impact this has on the film, they might as well have been just best friends. It's a shame the characters and themes weren't developed further.
The cast selection was strange and wonderful, although the acting was poor in places.
Don't start with expectations of sex and fountains of blood, just relax and enjoy a film about two very different friends who become vampires.
