It all depends. I like the idea of a universe just going on and on, so long as the material stays interesting.
The problem is that the universes must be fed, so studios will put whatever they can on the screen to keep justifying the making of each movie in said universe. That's why 3 movies was usually such a good number for good material. After that, you just run out of good ideas.
The only place where this doesn't hold up is the Marvel universe... The reason being is that they don't have to keep coming up with new ideas, all of the ideas are already in the comics and tested. So they know what material works and what doesn't. That allows them to use the main story points as islands within the universe and they can build bridges between each of those islands.
Making movies for the sake of making movies will make some money, but in the end it will never make the possible money that it can if the material just isn't good. Unless it's a Pirates of the Caribbean movie, then God help us all.
