day 07 - the most surprising plot twist or ending

Movies do not surprise me with their ending, or twist.  Minor twists sometimes get me, here are a few:

D&D lightsaber in dorkness rising

Oxley not knowing Indy was Mutt's dad, as it was semi-implied that he knew earlier in the movie

That the military guys said no to going in to save the world in Transformer: Dark of the Moon, even if only for a moment, yes I know, they were no longer active military, but growing up military makes that action seem off to me
