Unfortunately, there isn't a lot of "good" science fiction out there. Here are my ideas of what the science fiction genre should strive to emulate:
Contact
IMDBBlade Runner (directors cut)
IMDB12 Monkeys
IMDBStrange Days
IMDBFirefly (tv series)
IMDB and Serenity (the movie sequel)
IMDBTaken (tv mini-series)
IMDBJohnny Mnemonic
IMDBPush
IMDBPitch Black
IMDBThey key for me is that the setting and plot seem plausible so we can relate and that the climax or conclusion is not too fantastical to believe. Too often science fiction goes too far and becomes unbelievable. Or they aren't able to do the above on a shoestring budget.
I wish there was a new genre of science fiction named "science fact", where the story limits its use of science to proven facts or accepted theories.
