So ... for best trilogy I use the metric of top quality from beginning to end ... which three movie series hit on all cylinders all the time ...
I'm sorry ... Matrix II sucked big time ... I'm sorry, The Two Towers sucked straight off Tolkien's own hand ...
Whereas all three Shrek movies put my whole family on the floor laughing ... more so than LOTR ... I had introduced the kids to Bored of the Rings long before the movies came out ... we couldn't stop laughing through all three movies ... God that was embarrassing ...
