Amateur writer's opinion here: This had a BAD plot.

Rating: 1/10 (26 May 2019)

SPOILERS.
If you are searching for a well constructed plot, just move along to the next title.
Being a sci-fi writer myself, I am actually embarassed to see such a movie receiving 7+ review points, when the story is just so poorly written. So many plot holes. So many unanswered questions. SO... MANY... lazy solutions on screen!
So, clones living underground?
Who has cloned them?
How the HELL does an abandoned clone-station hold clones from people that have not even been BORN YET, back in the 80's? Because when the red-family appears at their doorstep, they got clones of the children too, don't they? Were they cloned long before, or did the government scientists miraculously re-appeared at the station just to bring in the clone's offsprings?
Why couldn't young Adelaide just go back upstairs, when the staircase was just 50 feet away from her room? The station is VERY small, and no one was guarding the amusement park above. She KNEW her family was up there (being a real human, she knew how things worked).
Where did the clones find so many golden scissors? How on GFKING earth did they communicate between different stations in order to decide wether to wear red, or pink, or fking striped clothes?
Anyways... the plot hole list could go on, but, you got my drift.
Again, being a writer, I CANNOT respect a history so lame, when there are so many important details like this left aside.
Terrible, terrible movie.
