sci-fi is just something ells
horror, drama, thriller, romance etc all have a realistic element to it, sci-fi is far from reality, i like it, from time to time, couldn picture myself watching it all the time (like some people do, some)
i watch blade runner from time to time, also alien/aliens/alien3
others favorites are: 12 monkeys, thx1138, invasion of the bodysnatchers (1956), The Thing, forbidden planet, target earth etc.
Sci-Fi is cool as long as it doesnt get too complicated
