>>“A lot of people do a lot of things, then the film ends.”
That describes most action/sci-fi movies made after CGI became the centerpiece of movies. If they have a plot at all, it centers around “stupid humans destroyed an environment and caused a war/plague/dystopia but now ONE smart human has the key to fixing it”.
Go to see Ex Machina; a small budget movie that does a lot with what it has. It is in limited release, but a good plot and acting IMO.
