Silent Running ★★

So I watched this when I was far to young to get it. Now I see this as a interesting concept that could have been done so much better. In this movie American Airlines is flying giant forest arks out by Saturn. Bruce Dern plays the guy who maintains the forest who decides to risk it all when home base says. "Hey go ahead Nuke the forests and come on home." This is a slow movie and is mostly a exercise in special effects that were cool for the time
