Blagh, shakycam.
It can help create the right mood and add tension if used sparingly and responsibly, but in newer movies and TV shows it's my biggest pet peeve (even more than the overuse of washed out color palettes)
The camera doesn't need to shake all the time. Let me look at what's on screen for a second or two, please! Does the cameraman have Parkinson's? Are you trying to give people headaches? Why does the sun come up?
That being said, I can't wait for the anniversary ESB:R clip. Just don't show us too much, because I have no self control and will look at anything thrown in my lap. Not that I need to worry, I think Adywan's been proven responsible when it comes to trailers and clips.
