review: As a SciFi fan who can spot a &#34;fake&#34; a mile away, Prometheus left me somewhat disappointed.  Although the premise was good and the movie started off fairly strong, the characters turned out to be quite shallow and the second half of the movie was cheesy.In my opinion, this was NOT worth the money I paid to watch it on my Roku.
question: Why do I have a great concept?
the premise was good
