I don’t think people would want to watch the second film so much that they made it the third best selling in the world if they no longer cared about the first. The core of the plot in each is very easy to remember. I’m sure many people just watch for entertainment, but that doesn’t take away from the films’ quality. One could enjoy The Matrix for the fight scenes, but it would still have its value as a statement on conformity, a look into the simulation hypothesis, or the trans allegory that it is, among other things.
