Trilogy Meter

This blogger has rated his enjoyment of several popular movie trilogys (many of which, initially, had no plans to go past the first film).

I agree with most of them, however....

• I think the third "Indiana Jones" movie was not nearly as good as the second
• I think the third "X-Men" movie was, after a second viewing, as good as the second one

I do agree that several sequels were as good as or better than the original, like "Alien", "Star Trek" and "Mad Max" (thanks to a bigger budget and Tina Turner's wig).

What do you think?
