When The_Matrix was released in 1999 on March 31, so many people were amazed as to how cool this science fiction movie was, and still is.
For many, just one Matrix movie was enough and a person could leave it at that. However, several people liked how the story continued in The_Matrix_(franchise) universe.
Perhaps the 4th Matrix movie might just be considered to be like some bonus material to the overall story-line. However, it does provide some interesting updates.
There doesn't seem to be any more Matrix movies on the horizon. https://en.wikipedia.org/wiki/The_Matrix_Resurrections#Future
