Yeah, the last "BOO!" was entirely predictable, at least to me.

However, since that's the last bend before they return to disembark, you can hear the sting when you're waiting in line, and some people obviously DIDN'T expect the last scare--there were some genuine shrieks. It was fun just for that.

(Also I like how one guy in the vid is yelling "Wooo!" in a rather perfunctory way, like he knows that's what you're supposed to do on roller coasters, but his heart's just not in it.)
