I haven't seen this movie for 22 years, until today!
Oh MAN, did I miss out on a certified addition to my movie collection!
I mean, I saw it back when it was released, either in the cinema or on VHS rental (can't remember which) but damn, did I re-enjoy it today! I remember most of it as well, except what the killer's occupation was.
But damn, is it a great science fiction and (essentially) time travel movie with cops and firefighters! Oh, and baseball! And New York, where I've personally visited!
