The Prestige (movie review)

My initially negative impression was mollified through my own lecturing about it to Alexia this morning. I realized it treats of a deep existential problem that'll confront the first Tesla types to walk through a transporter, like on Star Trek. Is that really "me" on the other end of the line, or do I die, to be replaced with my replica? But then it's not like we haven't faced this question in other contexts. These stage magicians certainly get a close look at the problem.
