Incomprehensible good ratings

Rating: 1/10 (17 August 2015)

Let me see:
-visual effects unworthy of a 90s sci-fi movie. -Sustained bad acting. -A plot that (consistently) borrows from Starwars and Blade Runner.
How can this be a top 250 movies ever? Am I missing something?
Being a movie fan, I tried hard, really hard to find out from where those great ratings came from. If it was not on the acting, nor on the special effects, nor on the plot then there must be something in the characters or perhaps on the movies capacity to transport us into another world. Wasn't there either.
Avoid.
