Keeps you guessing BEYOND the end!

Rating: 10/10 (24 December 2019)

Saw a review that said this movie "keeps you guessing till the end." If you take the "solution" at face value, I'd suggest you are missing a lot, and many things remain unexplained.
I want to avoid spoilers -- but I'd suggest there is much more to the conclusion than "meets the viewer's eye."
