I think they should have just left it at part 2. To me it seems that anytime a movie goes further than part 2...they make a mess of it with certain exceptions of course.....
how can you say that when there are many movies which are past the third sequel in their respective series
such as matrix revolutions which is coming out very soon
LOTR:the return of the knig which also is coming out soon
and how about the legendary star wars series of movies
