I owe DreamWorks Animation an apology. Since February, I have been criticizing its upcoming movie Trolls. Between a strange visual style, a bland-looking synopsis and, worst of all, twerking trolls shouting “YOLO!”, I have not been looking forward to its release, and I still dread the day I have to review it. But I have been consistently framing it as a low point for mainstream American animation. Recently I’ve seen the error of my ways.
