Though the idea that there can be "too much of a good thing" is worthy of debate, movie studios seem to believe that there can never be too much of anything—particularly when it comes to making a sequel to a moderately successful flick.
While some movies are launched with every intention to make it a franchise, more often than not, the sequels fail to be as good as the original (with some notable exceptions of course).
And considering that this trend is fairly consistent, regardless of the quality of the first film, the sequel can be a lot of awful heaped onto bad.
Sports movies—in particular—seem to suffer from this phenomenon. Few films about something sports-related seem geared toward a sequel and there are plenty of bad movies that should have never been made to begin with (let alone, allowed to multiply).
Sometimes a sports flick's sequel is a bald cash grab riding the coattails of a solid, successful film. Other times it's just one of those bad sequels we've come to expect. Or, maybe it's just a head-scratcher.
These are unnecessary sports sequels.
