My husband and I just watched 'The Prestige' which I have to say I found riveting, and for the first time in a long time I was actively watching a movie with all of my attention trying to figure it out - and got about 80-90% of it, but not all of it. That might sound like bragging - and I suppose in a way, it is - but for me, figuring out the mystery is the whole point of watching a movie. It might drive my husband crazy, so I try not to do it out loud while we watch television or movies, but I gotta say, it was a joy trying to figure this one out.
Also, I think he enjoyed me watching it and not quite figuring out every wrinkle. So, that was fun.
"Elsewhere, Within, Elsewhen," by Cat Rambo
This story comes from Beyond the Sun, and it's wonderful. First off, it's SF with queer characters in a future where no one so much as bats an eye about that. Second, it's about the characters and their mental and emotional state, but the background of the alien world provides the mirror and a physical representation of the character turmoil, and it's done perfectly.
Third, it's just so damned smart.
I'm not sure I can explain this one without giving too much away, so I'll just give you the set-up and then promise you the rest is phenomenal in execution: it's about a man who believed he was about to make it as a colonist for a settlement on a new planet, but a technological advancement makes him redundant and he loses his spot - only to regain his spot when his partner qualifies for the position, and spouses are included. That he wasn't going to do the same is just one thread in the fabric of their under-strain relationship, and the way this story folds that issue into the ultimate conflict is just so damn brilliant.
