A great question

There are lots of definitions for SF, and I myself tend to be rather strict
about it, though within the definition the range of stories is quite broad.
SF is a story about change; a new paradigm. Its fiction set in a world that
differs from our everyday world in a way that importantly involves science or
technology. This can include sociological changes as well as changes in
hardware. It can include stories set in the past, but mainly in the future. I
would include doomsday scenerios and post-apocalyptic movies of every kind (On
the Beach, Dr Strangelove). It includes alternate worlds and stories that exist
in the modern day but with slight twists(Fahrenheit 451; Truman Show) It differs
from pure fantasy in that even seemingly magical changes should have some
rationale beyond simply saying its so for its own sake, as long as its fairly
internally consistent(such as Star Wars). Scientific accuracy is a plus, but may
take a back seat in favor of excellent high concept or speculation.
As far as rating them goes, its a mix. Obviously I had to have some personal
enjoyment in watching it, entertainment value is basic and important, but I also
like intelligent, sober movies or movies that totally twist reality: A range
which includes Andromeda Strain, a dry but engrossing presentation; and Matrix,
which totally turns every expectation on its head. A movie with complex themes
that may not be executed as well as another, less demanding film may not rate as
highly, as in the case with Slaughterhouse 5 compared to Star Wars. I tend to
like movies with a message..some sort of relevency, these will rate higher
usually for me. A sense of wonder is perfect for the visual medium and I also
think its important. Basic filmmaking techniques and the normal aspects of any
good film also applies.
