Imagine if Pixar, the people behind films such as Toy Story, The Incredibles, Up and Wall-E, decided to make an adult comedy. Imagine if they gathered together a who's who of funny people, including most of the cast of Superbad alongside actors like Kristen Wiig, Paul Rudd and even Edward Norton. Imagine if they made a movie specifically dealing with the concept of religion, and that the world would be a better place without it.
Now imagine that Pixar were also really, really bad at making movies. Imagine that they lost their ability to effectively tell a story, to create interesting characters, to make movies that resonant with their audience. Imagine if everyone working for Pixar suffered a severe head trauma immediately before putting pen to paper, instantly putting their mental age back by decades.
The result is Sausage Party, a film that means well.
