Went and saw The Square last night.
Found it entirely too long, dull, and uninteresting. Some funny parts, but not worth sitting through the rest of it. Each and every scene was too long with lingering shots where nothing ever happens. There's no payoff for anything. Even the best scene of the film (a black tie dinner affair that goes horribly wrong) goes on for way, way too long and the resolution is meh, with the scene not playing into the plot in any way other than to show the main character is a dolt.
I've read that it's a scathing takedown of the art scene, which I'm not a part of, so maybe it was over my head.
