Assuming you are of the "I want a good film" rather than "I want a shot for shot remake of the cartoon" persuasion they appear to have a nice aesthetic and at least broach some of the ideas covered in the cartoon. The trailers do not give too much away either which is nice (it is a future film in which bodies are repaired with robot parts and brains twiddled with, of course there is going to be a "you might not be what you think you" are villain/subplot). Being trailers I can't tell how much they are going to go in for the issues in the final cut and instead might end up with cheesy action film sprinkled with a few disconnected philosophical elements, but there is a hope. The director, Rupert Sanders, has only the one feature before this (Snow White and the Huntsman), you can watch one of his shorts on vimeo (can't really link the black hole one here as it is nsfw), but the producers have done some good stuff before now and the US rating does seem to be going for R which is nice.
