the film is imho about decisions, or better the lack of the latter by the guys who conceived it. Whats this film about: some end-of-mankind future (in detail not very convincing). some drama, an idea of redefining 'love'. some serious plot holes, some special relativity trivia. And some nice-to-look-at-transformations from 4d to 2d without any use of riemannian geometry.

Its by far a or *the* reference for a top-scifi-movie.

but go ahead and see it. Judge for yourself. maybe in our days, scifi-movies can only be achieved by scientists themselves. Examples i would recommend: "the elegance of the universe" and "the fabrics of cosmos"
