Wow, could be a story of my life...I was born in the 1950's and from the time I was about 8 years old I dreamt about space travel and rocket ships. I never made it that far, but I also have never stopped dreaming about it. Some movies are based off of unfulfilled dreams, aspiring enthusiasts, like me to never relinquish our most inner passions. Also, a movie like this formulates its own ending and allows us to imagine ourselves in that narrative. A nice finishing to an enduring personal fantasy. Richard Dreyfuss portrayed his character so realistically I found myself wondering (after the movie) was there any veracity to his characters likeness coupled with his great acting abilities? You have to wonder; I know I do.
