I don’t watch trailers for movies I don’t want to see, don’t watch trailers for movies I want to see to avoid spoilers, and spoil movies I might see by watching a trailer.
I need trailers for trailers that don’t spoil a movie. Didn’t we used to have trailers that just whetted your appetite?
Btw, saw Boyhood today with my son (not having seen a single trailer) and it’s incredible. ★★★★☆
