The answer is no. Unless the need is to make a follow up to the film that created the "blockbuster" and earned the studio tons of cash in which case the studio answered "yes".
There was no need to make any other ones, I agree. Jaws 2 isn't awful, Jaws 3(D) is pretty dire but The Revenge seems to be understood to be one of the worst films ever made. Also, as far as I can tell, it was released theatrically, so I'm not sure about the TV movie aspect of which you speak...
