X-men was a rebirth for comic book films. After devolving into silliness in the 90s it was the first to show that with a compelling cast and talented writers super hero films could be more than just kids movies. In particular it is highlighted by iconic performances by Patrick Stewart and Hugh Jackman as Professor X and Wolverine, respectively. Unfortunately, the film has not aged particularly well and has been eclipsed entirely by Disney's MCU, but it should be given credit for starting the modern super hero film phenomenon.
