Personal Shopper
I had high hopes for this film, given it received positive word of mouth. Unfortunately it is rather mediocre, with Kirsten Stewart being a surly sort-of-paranormal who acts as personal shopper for a fashion model. Kirsten may or may not be variously stalked, haunted, psychotic etc. It's been done many times before and I doubt this is the last.
It did, however, lead to a general chat in my house about whether ectoplasm was real and lots of Googling to prove it one way or another. We realised that a lot of the so-called pictures of ectoplasm looked like silk curtains being spewed from various orifices of 1920s psychics, which led to the conclusion that it would be good to have a pair of scissors in a ghost fight.
