Why is this low rated?

Rating: 9/10 (22 April 2020)

I first watched this in the year it came out and today I rewatched and I loved it in both times! I really can't understand the reason for the low rating and critics. Interesting background story, great story telling, amazing visuals and special effects, cool action scenes, unpredictable twists and surprises with a beautiful and touching ending, what do you want more? This is probably one of the most underrated sci-fi movies ever but yet one of my favorites!
