DVD is definitely the best format for watching a sci-fi movie, as viewers are usually treated to theater-quality surround sound and a digital picture that presents the film in its original aspect ratio. But in some cases, the only way to watch a certain fantasy movie is by purchasing the VHS version. This is because not all movies have been released on DVD yet, making some science fiction VHS movies hot commodities amongst collectors.
A good example of this is one the most popular sci-fi series of all time: Star Wars. Lucas made several slight changes to the original trilogy when the films were released on DVD. Therefore, the only way to watch the trilogy as it was first released in theaters is by returning to the VHS copies distributed in the '80s and '90s.
The original versions can still be purchased on VHS, letterboxed in their original aspect ratios, and priced affordably. But Star Wars isn't the only instance where a movie isn't available on DVD; there are many older, lower-budget cult sci-fi movies from the '70s and ‘80s that haven't received the DVD treatment either. In such cases, VHS is the only option.
