YMMV: Shrek the Third
- Badass Decay: Shrek himself, which was noted by several reviewers. In the first movie, he curbstomped Farquaad's knights. In the this one, he's much softer, and didn't do much to fight back against Charming. Shrek gets some of his badassery back in Forever After, but is largely overshadowed by the Proud Warrior Race Guy ogre tribe.
- Filler/Padding: The entirety of Shrek the Third could arguably be considered this in relation to the series as a whole. The film has no major plot events that affect Shrek Forever After (aside from witnessing the birth of Shrek and Fiona's children) and none of the newly introduced major characters even appear in the subsequent film. Seriously, try watching Shrek, Shrek 2, and Forever After in that order while skipping over The Third. It has almost no bearing on the other 3 films. It actually makes even more sense that way, when you consider Rumpelstiltskin's appearance in this one.
- Parental Bonus: The two birds that perch on Snow White's shoulders just before she sics all the forest animals on the evil trees? They're woodpeckers.
- Parvum Opus: The general consensus states this movie as the weakest of the franchise (though 4 is pretty heavily divided).
- The Scrappy: The ogre babies in the third movie; they only appeared near the end of the movie, but many people dismissed them as a kid-oriented Tastes Like Diabetes marketing gimmick. Arguably Rescued from the Scrappy Heap in the fourth movie.
