I found this on kottke.org, an explainer video (from the guys who made those excellent Star Wars clips illustrating how shit the original trilogy is). This newer video cleverly describes how all movie trailers are the same, by splicing them all together so you can see there's some formula applied to get us all wet for whatever is coming. Consider me manipulated like the rest of you.
Consider I've stopped watching trailers because they spoil so much at the expense of building any kind of atmosphere or anything unique, standout. This provides even more of an incentive not to watch trailers until something original comes.
Maybe not Game of Thrones trailers btw as it's not a movie and it had David Bowie in it! ;-)
