This movie doesn't suck but you have to have an open mind that it is set in an alternate universe where cloning is possible. Period.
The acting is great, the plot is decent. There could have been a bit more plot and character development but honestly, this is a very solid sci-fi/horror film. Its more suspense than horror really. Mia Goth is perfectly cast.
I guess I would have liked to have seen some flashbacks of the group doing bad things or some more development of their past things.
Watch with an open mind.
