Future shock

Saw Star Trek on Sunday, very good it is too. Enjoyable, well-paced, exciting and with enough humour to be fun, rather than irritating (as shoe-horned in humour often can be in action films).

Two thoughts though.

One: Why in sci-fi films (most famously in Empire Strikes Back) do space stations / ships of the future have a vast inner section that plummet downwards into nothingness where the villain and hero always end up fighting, balancing preciously on the edge of narrow walkways and gantries, often leading to the villains demise? All that technology and they don't even bother building in a few handrails.

Two: I think the creator JJ Abrahams could be from the future. Both Lost and Star Trek contain time travel elements and the more I think about it the more I wonder if perhaps he is just normalising us to the idea of it before he reveals his true intention.

That is all.
