For those of you (unlike me) who have modern systems (1080p display and an audio receiver that uses the new HD/lossless codecs,) what are your favorite movies to use to really show off the great quality that BD can exhibit? I mean odds are you wouldn't use a movie like "Gangs of New York" or "National Lampoon's Christmas Vacation", so which ones do you like to use to prove to your friends & family that you weren't crazy to spend so much money in your system?
