The Alien franchise has been going strong since 1979, even though many fans would argue that most of the sequels don’t measure up to Ridley Scott’s original film.
While he has been critical of the Alien sequels, he feels differently about James Cameron’s Aliens and about Cameron himself.
Scott himself has never been shy about admitting that sequels to his movies made by others were substandard.
While neither of Scott’s prequel Alien movies were as well received as the original, they were able to keep the franchise rolling.
