the biggest letdown in movie history

Rating: 1/10 (4 May 2017)

I've never written a review before. The only reason I'm writing a review for Prometheus is because I saw on IMDb that it is currently rated 7/10 - about 6 points too many.
Alien is the best movie I've ever seen. So because Ridley Scott was directing Prometheus I was expecting something special. What a letdown! Ridley Scott has directed so many great movies I still find it hard to believe that he actually directed Prometheus.
Why is this movie so bad? One reason, the characters; there was not one of them I cared about. The only decent parts of this movie were when each one of them died so that myself and the other tortured viewers no longer had to endure their unrealistic one dimensional performances. If you want to see how bad the characters in Prometheus really are, watch Alien and Bladerunner then watch this abortion of a movie after. You'll be amazed Scott directed all three movies.
The one positive outcome of Prometheus is that it proved that special effects alone are not enough to make a great movie. We viewers want a plot and characters we empathize with and care about.
Alien Covenant is released in three weeks. I pray that Ridley Scott doesn't betray his viewers with another Prometheus, but entertains us with a real Alien movie with Aliens we are petrified of and characters we care about. Please Ridley, no more letdowns!
