I've seen Hero and also City Hunter, are you sure it's the same director?
Hero was very artistic, it was much like Crouching Tiger, Hidden Dragon. It did well in Asia i think. I didn't like it very much, it was very over-hyped.
City Hunter is a weird film. In it Jackie Chan plays some sort of Manga star! There are some good fight and action sequences, but overall it's one of his poorer films.
As for The Transporter, i bought this blind, i did not know if it would be any good, it was immense! The action sequences are great! I recommend it to any action movie fan.
