Mission Impossible in IMAX

Perhaps it was the IMAX experience that enhanced the movie, but it seemed to be the best of the quad. Is it possible that a 3rd or 4th can be the best of a series?

I think the IMAX presentation had a lot to do with making the movie better. And I think a 3rd of 4th can be the best in a series. They typically aren't, but in cases like Lord of the Rings or Harry Potter, most say the later ones are better than the original.

How many series can you name with more movies than a Trilogy? Rocky for example...

I think it was Paula Patton and the Russian chick that really enhanced the picture.
