The DreamWorks Trequal Paradox

Created by the youtuber TheOdd1sOut, The DreamWorks Trequal Paradox is a phenomenon where a DreamWorks sequel is as good (or better) as the original, but the 3rd movie is sub-par.

However, there's one franchise that doesn't follow the DreamWorks Trequal Paradox™ and it haunts my dreams (works).
