Toy Story? Or the ten sequels that followed?
Now, think of the same movie but replace the ecosystem of toys living in a child's bedroom with that of food living at a supermarket. Replace the child friendly themes with Seth Rogen, too, and you got yourself a Sausage Party.
What this translates into is a sausage (Rogen) whose chief ambition in life is to get into a bun (Kristen Wiig). More importantly, they live in a computer animated supermarket where they recite a hymn about the wonderful heavenly world that awaits when the gods (humans) purchase them and take them along and away from the shop. Clearly, our groceries are in for the shock of their lives when they discover what their post supermarket fate actually is, hence a movie full of theological themes. Let me make it very clear that in this discussion that does not try and hide its religious aspects, secularism does win; on the negative side, being this is a Seth Rogan movie, the answer to all questions is sex.
Surprisingly enough, there is a second theme to the movie revolving around the Arab-Israeli conflict. Escorting our lips & asses made hero is a Jewish bagel (Edward Norton doing a very Woody Allen character) and a Palestinian lavash, and as you can imagine there is a lot of antagonism between these two. As you can also imagine, they would also discover they have much more in common than not, and as you should also be able to imagine this will lead them to have sex.
Look, Sausage Party is a very silly movie in spite of dealing with heavy themes (how they manage that should be the subject of a university course). More importantly, Sausage Party is a movie that clearly demonstrates the absence of adult animation movies is a failure of the free market.
Overall: 3 out of 5 crabs.
