The original Shrek was a breath of fresh air with it's flip on the fantacy arch types like monsters, princes, and knight's in shining armor, and its sly fun poking at everybody with there pop culture references. Shrek 2 took this forumla and expanded it to answer the question of "what happens after happily forever after?" expanding it's flipping on the most central of all fantasy arch types, Prince Charming and the Fairy Godmother, and that is where the series should of ended. Shrek 3 however felt like the writers had used up all the good ideas on the last two movies and was written by the marketing department or the production company to maximize profits of the kiddies. Shrek 4ever after (did they REALLY have nothing else to call this) I am not going to see, ever.
Let a parody have to many sequels and it is doomed to become what it makes fun of.
