Good, not great

Rating: 6/10 (14 May 2019)

Pros: Good acting especially by the star, some good sequences and efforts by all
actors, an original storyline, and the significant & unexpected twist at the end makes me want to see the whole movie again (will wait for Netflix or Amazon Prime).
Cons: Plot holes are an understatement. Willing suspension of disbelief is one thing, a logistically un-believable backstory is quite another. Without going into spoilers, the DNA element alone is mathematically impossible. Then figure travel, international immigration factoring into a supposedly US-based phenomenon...these matter a lot. The script straddles the two cliffs of ambiguity and depth, doing neither one very well. The morality is not thought through, and there is no real message.
Neutral: What is with all of these 1 star reviews, saying horrible without any explanation. Why was it boring, hilarious in the bad way, terrible?
