I can't say enough good things about this movie. Clever, well-acted, well-written, and constructed with an intricacy and a clarity that just blows me away. This movie is just plain solidly good.
Having said that, I'm amused by the critics I've read who make comments re this film to the effect of "Finally, a sci-fi movie directed exclusively at women!" I'm all for sci-fi directed at women. But let me tell you, as a hetero male sci-fi geek, I have no problem at all settling down to watch a story about time-traveling lesbians. Are you kidding? What is perhaps a bit more unusual in sci-fi is the portrayal of realistic, three-dimensional female characters, and the very natural, and, I'll say it, feminine way that they deal with the bizarre events that befall them. Particularly in genre movies, faux-feminist "strong women" are often depicted as essentially men in female bodies. The central characters in this film are strong people (well, one of them becomes strong) and it has nothing to do with gender inversion, or reversal, or some sort of overthrow of the male paradigm. Or, if that stuff is in there, it's buried deep enough that I didn't feel beat over the head with it.
The world would be a better place if the marketing machine was put to use convincing people to see movies like this instead of, to take some recent examples, Pearl Harbor and Planet of the Apes. The Sticky Fingers of Time made me feel better about being alive. I want the poster. Bravo.
