What the heck was it?

Rating: 2/10 (25 November 2019)

So it's too nonsensical (like where did the underground people get their clothes - from underground sweat shops in China?) to be a science fiction. Must be a horror movie, but with the out of place, lame, tongue in cheek attempts at humor, it's really not scary. I know, it's a social commentary and the underground people are symbolic of the downtrodden and ... nope, not that. Wait, it's an allegory for self-exploration - nope. All a dream? None of those, and the twist at the end can be seen a mile away - but don't care enough about the superficially rendered characters to care about the twist.
I got it: It's a cynical attempt to make money off the success of "Get Out".
