Not bad, and adds a twist to the genre - Spoilers

Sure the cloning doesn't stand up to much scrutiny and the behavior of the clones at the start makes even less sense, but the movie settles in and explores the idea that clones are unique just like people. Being superior the clones suffer from a a fatal flaw, arrogance. As they interact it becomes apparent not all is as it seems and that leads to the twist at the end where one of the clones winds up as part of the trio. It's not Invasion of the Body Snatchers or even The Broken, but it was enjoyable enough.
