Leave it to the Americans... (spoiler-ish)
...to show the FINAL scene of the movie in both the trailer and on the poster/DVD-cover.
I know this isn't the first movie where it's done, but in almost every horror movie trailer from the last 5-10 years, the ending shot is shown.
WHY do they do that??
(Not that I care with this movie in particular, haven't seen it, never will, I love [rec] and it's more than adequate for me...plus, I hadn't seen the ending beforehand.)
...just sayin'...
