25th Anniversary Screening.
I watched this in IMAX five years ago for the 20th anniversary. It was extremely awesome. Tonight's presentation was a little more underwhelming, mostly because someone decided it'd be a good idea to crop the aspect ratio. When Grant and Sattler see the Brachiosaurus for the first time, its head is completely cut off from the screen! I'm sure not everyone is bothered by this sort of thing, but it was kinda disappointing.
Anyway, Jurassic Park is still a classic, so there's that. The first T-Rex attack is an all-timer, that roar damn near melted my face off in the theater.
