The X-Men films have been continuously produced for over 17 years. They have made Fox a lot of money in addition to being generally well received. It seems like there is no stopping them. While it may often feel like DC and the MCU have cornered the market on superhero films, Fox has done an excellent job at remaining in the public eye and garnering favor through attempting to produce quality work. This trust in their films has led to financial success and it is impressive seeing them make incredible Marvel films outside of Marvel Studios. Their longevity in remaining a worthy studio is impressive in this overly-saturated superhero market.
