It's so good because it keeps apart concepts that are rarely implemented by
the same people.
Model is usually non-heavily reused (except maybe in applications), and is
implemented by a development team.
View is how you actually show the data (the MODEL) and usually is
implemented by some script programmers (JSP, servlet) that don't need to
know how the application works "behind the scene"; also web designers come
into play; controller is usually the work of web designers (for HTML and
perhaps some javascript programming)
it may also be done by a programmer who constructs an applet or application
to front-end the development.
This model clearly separates some kind of work(and expertise) from another;
it speeds up development and enforces 'black-box' code reuse (you don't have
to know how some things work 'inside'). And of course, it enables you to
manufacture an specific component/component-set that will interoperate with
other components, in any part of a development. This overall points to the
objective of developing rapidly complex systems that scale
mathematically(i.e. their performance is directly associated with the number
of server machines that run your application).
