First two-thirds are intreguing. The rest is a mess.

Rating: 4/10 (2 December 2018)

The first two-thirds of this movie is intriguing, where you are waiting for four seemingly unrelated threads to come together. It is interesting to see some of the mysteries come to light. The main thread is about Betty, who just moved to Hollywood in search of an acting career. She is staying in her aunt's apartment. But Rita is also staying in the apartment, a victim of amnesia. Rita has tens of thousands of dollars in cash and a strange key. That is the main mystery: What happened to Rita?
The problem is that the answer (OK, there really is no answer) involves time warps, body switching, and alternate universes. And none of it makes any sense. It's utter garbage.
The screenwriter had a great idea for a mystery, but had no idea how to conclude it. Perhaps he dropped LSD one night and whatever came into his mind he put in the movie. That's the most plausible explanation I can think of.
