Real Thriller Opening Analysis

I like this thriller opening especially because i think the idea of 'less is more' plays an essential role. With the shot of the polaroid developing in reverse taking up most of the opening time, yet it seems to make you want to keep watching to actually see what is going to happen next. It isn't till nearer the end of the shot you actually notice that its developing in reverse, then it eventually moves onto the next shot which then you understand a little more of what is happening in that particular scene. By the end of the opening, you get the impression that there has been a murder of some description and this character has taken a picture of it for unknown reasons. The opening is effective because it leaves alot to be worked out by the viewer without giving so little that there isn't anything to hook them in.
