For me I actually like seeing trailers before the movies. Personally I feel like the trailers are part of the experience and I can’t help but feel some disappointment when a movie starts with no trailers in front of it.
It's not the trailers most people are mad about, but ads for products that they stick before the trailers even.
Trailers have been a big part of the movie-going experience as long as I've gone to theatres. Coca-cola, Ford and Government of Canada ads? Not so much.
