Maybe not the best movie directed by Clint Eastwood and maybe not the best space movie but certainly enjoyable enough to watch. The scenario is not highly believable but then again it's just a movie. I seriously doubt that those elderly men would pass any of those NASA tests, but Clint Eastwood, Tommy Lee Jones, Donald Sutherland and James Garner are apparently cut out of another wood then us. I thought all actors did their job like they should. There are no Oscar performances here but it doesn't really matter. It's a nice adventure movie where you don't have to think too much. The story is simple and I wasn't expecting much more out of it. Old guys sent to space to save the world. Mission accomplished...
