To start with very poor CGI like very poor for a film made in this day and age. Jurassic Park was made 30 years ago and holds up better.
Alot of unanswered yet valid questions for example.
Why are all the aliens the same species yet totally different sizes, can preform interstellar travel and have telekinetic abilities until the plot doesn't require them to. This makes it hard to take them seriously as a threat.
I understand its trying to be unique and it has some good ideas but the execution is not great. Its far to convoluted and has way to much of the crawling around when you could get up and run sort of annoying tricks and way to many inconsistencies
