I quite enjoyed mother!
It wasn't subtle or super deep but it was audacious, darkly funny, absorbing and aesthetically interesting. It took a while for the balls to hit the wall but once they did I was happy.
It, on the other hand was kinda boring. Over reliant on schlocky jump scares, the actors and cinematography were all good but the sound editing was terrible and cliche as was the soundtrack. The Stand By Me-ish scenes worked a lot better than any of the actual "scares." but if I wanted to watch a good version of Stand by Me I could just watch Stand by Me.
