An interesting premise fails to ignite amid an underwritten central romance and some clichéd plotting. An often eye-rolling ride.

It manages, nonetheless, to shrink all narrative possibilities down into a bitty best-of compilation that's notable only for some horrendously bad science and a career-low performance from Gary Oldman.

It's a wan, anaemic film.

For as much as there is a place for the heady and heavy in science fiction, there should be room for the simple as sweet too.
