Hard disagree.

2 had some pacing issues, but all 3 are amazing works of science fiction, the last 2 suffering from understandably not being able to top the first movie's reveal of "Your entire existence was a lie." 2 and 3 expand on the lore while visually presenting deep philosophical concepts, but as studios have learned, trying to appeal to the widest audience means not challenging your audience.

They have since gone so far with that lesson, it has lead to stuff like the new Star Wars trilogy, a plotless trainwreck of endless appeals to nostalgia so blatant I'm surprised they didn't have force ghost yoda turn to the camera and smile impishly like austin powers.
