This did for me what Star Trek and Star Wars were unable to do... make me excited about the possibility of a sequel. I don't think I've felt this for any filmed saga other than Lord of the Rings. Simply put, the film successfully carried me away to a mythic world of intrigue and wonder.
I should note, I suppose, that I have not read the novel, and have nearly no memory of Lynch's adaptation beyond its leaving me disappointed.
And, oh, I loved the soundtrack! Gonna have to pay more attention to this Zimmer fella.
