Fair enough! I can't remember any other major scares though. Did like the creepy figure in the headlights though - those half-glimpsed figures at the back of the shot always creep me out
Regarding the one-take thing, I thought it was obvious at several points where the in-built edits were concealed. I think some sequences would've benifited from traditional editing. Some scenes were hampered slightly by odd movements to make way for the carefully hidden crew . . .
