Bad casting, too long, great idea messed up !

Rating: 4/10 (16 February 2018)

The Captain and the scientist Elizabeth Shaw were mis-cast. Idris Elba trying to play a Southern black was laughable, pathetic, and his part contributed next to nothing to the storyline. The female scientist was immensely annoying, yelled and screamed a lot, very unattractive, came across as a tradityional sterotyped hysterical woman, sorry.
The movie just went on and on and on; At 1 hour 35 minutes I was praying for it to end VERY SOON! Cinematrography was excellent, most special effects very professionally done. The android character David (Michael Fassbender) was terrific ~ now that's acting! Charlize Theron did a great job, too, in a very difficult part. Smaller roles well-handled.
Btw, it was very easy to anticipate the big surprise regarding the guy who had financed the trillion-dollar venture!
Had the film been one hour 30 minutes, I would probably have awarded 6/10, but as it is, 4/10 is the maximum I can manage, and sci-fi is one of my most favourite genres.
