The year 2000 was 25 years ago? While that might not seem right to everyone, it is true, meaning it is an excellent time to look back on the first decade on this millennium. The 2000s saw advancements in CGI and the meteoric rise of the superhero movie, and it is still the decade with the highest-grossing film ever (while the $2,923,706,026 at the box office is impressive, 2009's Avatar didn't make this list). The best movies of the 2000s come from multiple markets, as many different international markets were in full swing by the start of the 21st century. From classic 2000s movies to underrated gems, great 2000s films come from many genres, from action to romance. In many ways, the 2000s feel like a transitional decade, with early 2000s movies feeling immensely Y2K and later films in the decade barely registering as nostalgic. So put down your flip phone, pull out the Blu-ray collection, and enjoy the best 2000s films.
