This movie is very good at going nowhere. It doesn't feel imaginative, playing off of a trope that has been done hundreds of times in the past, and it has been done better dozens of times in the past.
The Clone plot point seemingly fizzled out into nothing, with no actual closure. The same is done with the idea that the main characters could've been clones themselves, and nothing is established on that further.
The acting was decent, but the dialogue quality was lacking. The conversations felt stiff, and not authentic.
The music wasn't memorable, I have very little to say about that.
Overall, this movie falls completely flat on its face and is contrived straight to the bone. Do not recommend it.
