What movie series should have stopped after the first film. What movie trilogy or series should have never been made. Where the first was near perfect and the rest were never as good and in some cases even ruin the first?

The recent series that comes to mind is the Matrix. The first movie knocks it out of the park in almost every category. And then 2 and 3 were overloaded and too full of themselves. And then 4 comes out almost twenty years after that. There was no need, it was over the top meta and couldn’t come close to the originals magic. An older example would be Jaws. The first was incredible, a near perfect movie. And then 2, 3D, Revenge? All of which were unneeded and clear cash grabs. Is there a better example out there?
