Shrek was THE number one IP Dreamworks had, think about it, Pixar has Toy Story, Blue Sky has Ice Age, Sony Animation has Hotel Transylvania and Illumination has Despeciable Me. All of these still get movies, shorts, video games and merchandise to this day.
Dreamworks has nothing now, all their heavy hitter franchises are dead. Shrek, Madagascar, Kung Fu Panda and Dragons, all gone. What do they have now? Trolls? Boss Baby? LOL! Those are garbage and will never be as huge as their previous films. Dreamworks is dead.
