Weird plot that leads nowhere, with predictable twist(s)

Rating: 3/10 (24 May 2019)

This movie seemed interesting at first, because I listened to the reviews on it and heard good things. Well... I was tricked again.
The movie gives you a text card at the start to get you thinking about underground tunnels or whatever... not much meat on that bone to be honest. We dip into a boardwalk carnival in Santa Cruz where this little girl finds an old sideshow attraction that apparently is the entrance to a secret underground clone lab. Turns out her and her clone that live in this lab are 'tethered' and end up finding each other in this sideshow house of mirrors thing. The issue is that the clones are soulless, so they're inherently evil, or have gone crazy due to having no souls and being trapped underground forced to mimic their counterpart's movements above ground. (yeeeeah, ok)
Anyway, fast forward to the meat, there's a huge clone vs original battle between basically everyone. The clones have escaped the underground compound because they got tired of the lack of sunlight and eating rabbits. Basically we end up back at the boardwalk after clone apocalypse occurs. The lead girl goes back into the house of mirrors, finds the entrance to the compound, finds her clone again, kills it, and then leaves with her family... to where? Who knows. Mexico apparently, and no idea why. What's weird is after the clones have killed their originals, they join hand to hand to form a human chain across the globe... this includes going underwater... so I'm not sure how they're living through that since the clones are just as fragile as we are.
Turns out at the end that the original little girl was replaced by her clone at a young age, and then was the one who rallied the clones to the surface while the little girl's clone carried on about life... seemingly forgetting she was a soulless clone monster thing.
This movie was pretty ridiculous, boring, and all around poorly written with predictable twists and turns. I wasn't impressed. The big father who plays Um'baku in Black Panther was emasculated the entire movie... made out to be a giant wuss for the most part. Everything else was just a lot "huh?" and "what... why?" Like why are these clones hell bent on doing a hands across america (world) remake? Who made them... why was the project left and forgotten... why is there an entrance to it in a house of mirrors? So many questions and I don't even care if there are reasonable answers to them.
