My personal votes would go to both Jeepers Creepers films. I remember particularly enjoying the second one, though the first is excellent. Despite the questionable background of the director, these are two of my favourite modern horrors.
Jeepers Creepers 3 is due for a release this year apparently. Rumours are that Trish from the first film teams up with Jack Taggart Snr and Jnr to track down the creeper.
