Which would indicate that the payoffs were badly executed or badly written. If you consider Matrix good as a standalone, then that means that the content that was setup and paid off likely made up for the badly executed sets ups for later films.
Not necessarily. Like I said before, the first Marrix film sets up things that have no pay off in the first film, and wouldn’t be paid off until the sequels. (Stuff like if Neo would have broken the vase of the Oracle hadn’t said anything. The whole sequels seem to made just to pay off that one set up in the first film.) Whole set up and pay off is important, the Wachowskis found that not everything
needs to be paid off in order for a film to be enjoyable; only certain things need to be paid off.
The same thing could be said of the “Rebuilds.” Not everything
needs to be paid off in some form of a conclusion in order to be enjoyable. And certain open endings (such as the ones in the first Matrix film or the one in Eva Q) can be particularly fun or interesting for the viewer.
