When I first started to watch The Beyond I was upset that it was going to be one of those stupid amateur go pro type.
It turned out much better, I'm glad I kept watching.
I agree with previous critics that the events are outlandish and do not comply with our knowledge of our solar system. Nor with our abilities with respect to transplantation.
But when you get past that and realize that this is a Sci Fi Fantasy, you see that it is fun and interesting on that level.
It was engaging and slightly suspenseful, in that it wasn't obvious what was going to happen, as so many movies are these days.
There was lots of thought provoking instances, I found myself thinking about quite deeply. Ethical, Moral, Personal Struggles etc.
I enjoyed the movie and I'm glad I did not heed the rating.
