Recently I saw the new Nicholas Cage movie, Knowing, which Roger Ebert gave a glowing review as "intelligent SF." I can't imagine what Roger was drinking at the time.
This movie does what 90% of SF movies do: sacrifice sense and logic for special effects. It starts out well enough, with the planting of an intriguing supernatural mystery exemplified by one of the spookiest little girls I've ever seen. Then 50 years pass, the mystery is logically brought to life and begins to operate in the present, and I was genuinely interested. Where might this go?
Where it went, was off the rails. Before the end, we had an unholy mish-mash of supernatural, aliens, the Old Testament, life after death, and a giant solar flare. None of these elements is developed logically in itself, and they don't fit together in any way that could be accepted by anyone with an IQ over the speed limit. But, of course, that doesn't matter because it's "only SF," so anything goes.
Then last night I saw the French documentary The Class, which follows around a high school teacher in a difficult district as he attempts to teach his students. This was completely plausible, logical, and boring. My companion shifted restlessly in her seat. I fell asleep. I have taught in such a high school and so perhaps should not expect to encounter much that was new to me (except the French language), but I don't think anyone could be deeply interested in this for very long. Rational, but stultifying.
My next attempt at movies will be the caper-thriller Duplicity. Maybe that one will work.
