The movie that started it all. Directed by Andrew Adamson and Vicky Jenson, Shrek was a direct challenge to the traditional Disney formula. Featuring an insecure ogre, a hyperactive talking donkey, and a fiercely independent princess, the film blended toilet humor, adult-oriented pop-culture references, and genuine heart. It was a massive box office success and made history by winning the first-ever Academy Award for Best Animated Feature. Shrek 2 (2004)

The inclusion of "2011" is interesting, as the fourth film was released in 2010. It's a common practice for "complete series" bundles to extend their release date to a later year when the set is compiled, which in this case, is consistent with DVD and Blu-ray box sets that were released in 2011.

The era concluded with a shift in focus toward the franchise’s breakout feline star. Puss in Boots (2011)
