They've been naughty. So we shan't be nice. Rather than choosing the 15 worst movies (we skip a lot of stuff that looks atrocious), here are 15 matters of annoyance within the movies of 2015, whether the movies were decent or terrible. Vague/light spoilers ahead.

15 Grab Bag of Undelights
Afew I couldn't fit in below: Chris Hemsworth's wandering accent in In The Heart of The Sea often within the same scene. Is this First Mate Australian, British, or from the Bronx?; The way Mother Malkin's (Julianne Moore) red hair stays that way when she shifts into dragon form in The Seventh Son. That was cute with Madame Mim in The Sword in the Stone but in "realistic" cgi not so much; and, the perpetual agony of trailers that take you from the beginning to the end of a movie (Room and The Revenant are the latest victims) spoiling every story beat.
In nearly great movies (Clouds of Sils Maria 124 min), good movies (Saint Laurent 150 min.), divisive movies (I'm still making up my mind about The Revenant okay? 156 min), and arthouse curiousities (Arabian Nights, Vol II 131 min., Love 135 min.) alike the tendency in contemporary cinema is to let the camera linger here and there and everywhere and also to include entire sections that add nothing particularly new to the plot or our understanding of character or theme if narrative isn't the movie's main thrust. Don't misunderstand: a good lingering camera can be among the greatest of things but if you're running over 90 minutes please justify it with new information. Shave 10 minutes (or a lot more in some cases) off any of these movies and they're instantly improved.
