Only one minor pet-peeve: the "scientific" explanation they gave to her condition was utterly cringe-worthy. As in, they strung together some "scientific" sounding terms that are peripherally related to aging and tried to make it sound smart. Look, movie people, either do it right, or just call it magic, and those of us in the crowd won't want to throw something at you :)
I left the theater very content after this movie. Also, thinking to myself that if you liked this movie, you're very much going to enjoy Coincidences (if I can ever sell it!).
The film itself was pretty heavy on the science side of the Turing test. Hubby and I have read a great deal about this, and it's one of our favorite dinner discussion topics (yes, we are that nerdy...and I'm sure we've given some people some strange ideas if their table is within earshot of ours). I found it odd that the film's previews and other marketing make it out to be more "scary", which came across as a bit of a misnomer. Not one I was sad about, but just something to think about if you haven't seen it yet :)
