It has some good points, and some not so good points.

Rating: 3/10 (17 September 2019)

Bad points
1. Way too long ~2hr 20min, at lest 50 minutes too long.
2. Netflix categorised It as scifi, but there is no science here; none, not a jot.
3. I didn't care if the main characters survived. I actually hoped they wouldn't, which would have made for a more interesting end to the film, but it was all too predictable.
4. The acting... Well I suppose actors need to earn a living between good films.
Good points
1. Amazing CGI - I've done a bit in the past, so I can see the excellent work here.'
2, Excellent production in making the film.
3. Not quite the ending I thought it would be, so nice twist.
4. I did watch it until the end, (though I had a few lengthy breaks on the way), so I guess that's worth half a star (but I can't do 1/2s so rounded it up).
