PRO: a double feature sounds awesome
CON: AMC Theatre's popcorn is offensively godawful dogshit and actively ruins the moviegoing experience.
No really, a deciding factor impacting my enjoyment of a movie is how good the popcorn is since I almost only eat it when I go to the movies, and AMC's popcorn is f**king terrible and I go out of my way to avoid it. I'll deal with less comfortable seats or whatever if it means I get really good popcorn (I'm looking at you, Harkins Theatres).
