It rocked. I even made it through the giant bug scene (fortunately, there were no giant cockroaches. ech. Thanks to ladycelia for the warning. For the rest of the world her advice for the bug-phobic is to either a) use it to take a bathroom break or b) "cover your eyes until the crunching noises stop")
It was long, but very enjoyable. And Kong's martial artistry against the dinosaurs was as much fun as johnnyeponymous said it was. Kong Fu, indeed!
