I was really intrigued by the premise of this movie. And I sat through the whole thing, even though I started to fall asleep and had to turn it off and finish it the next day. Because in spite of the extremely interesting premise, it is too slow, and does not have enough dialogue, and just doesn't achieve the potential it has with such a premise. I love slow long powerful movies, like The Godfather, Interstellar, There Will Be Blood, Predestination, etc. But this movie is just slow, not powerful, even though it really ought to be, they just aren't driving the point home. This is related to the fact that there's not enough dialogue. The characters barely communicate, even when they really should be. When the clone son asks his "mother" important questions she always ignores him and doesn't even respond. You never get to hear them have important conversations about the premise of the movie and who he really is to her. And the movie ends abruptly. So for those reasons, the movie falls so far short of its potential. And because of how slow and generally uneventful it is, without beautiful shots to keep you interested (most of the movie is very dull and gray), I think that this movie won't hold the attention of most people. I give it 4 points for having such an interesting premise that held my attention for the whole movie, but other than that there are no impressive qualities to this film.
