Destruction of the Endeavour
Despite a somewhat dissappointing last episode, AWE does have on of the most outstanding sequences of the last few years: the destrcution of the Endeavor with Beckett walking down the stairs. When I saw it in the theater I was already impressed. I've seen it over and over again, it's one most excellent sequence. Technically challenging and a seamless cut.
Is there any other POTC sequence that you feel can rival that bit?
