"Science fiction films have come a long way since 1902's A Trip to the Moon. Various subgenres have faded in and out of popularity, but the genre itself has always been in high-demand. Now, a century later, there is a smorgasbord of science fiction films to choose from each year. This is especially true when you look at last year.
If you look at last year's sci-fi releases, you'll find a surprisingly varied combination of movies. Although they all fit in the grand umbrella of science fiction, each film approaches the genre in a different way. Some of the entries are epic in scale, while others are smaller. Some are concerned with scientific accuracy, while others just want to keep folks entertained.
This should be evident as you read the list below. In this list, you'll find the ten best sci-fi movies of 2021. Some of the entries are grandiose blockbusters; others are high concept indie darlings. They are all, however, worthy of a recommendation."
