Science fiction needs to be at least plausible given the right technology.
Fantasy can be anything. Any magic.
Blade Runner is scfi
Termintor is scif
Preditor is scifi

Hmm. Just looked this question up and apparently George Lucas agrees with you. I guess the Force would make it more fantasy.
What makes Star Wars fantasy and Dune sci fi?
Imho, if there is a plausible scientific component, however far fetched, and no magic, mysticism, voodoo, pseudoscience, ghosts, etc. it is scifi.
Most people just lump them together. Scifi/Fantasy section.
