Query: The worst movie I have ever seen

Silent Running is the worst movie I have ever seen. It has a ridiculous plot with terrible acting. The movie has no point at all. It is about some lunatic man who has nothing better to do than be obsessed with plants. How can you make a good movie about a single man, 3 robots (one that flies off into space) and a dome full of trees. This movie is simply an hour and a half of garbage. If they are going to make a sci-fi movie at least make it worth while! Watching this movie was a waste of my time!!!
