Sausage Party is an R-Rated animated film about...well...food. Just like how toys were alive in Toy Story but unknown to humans, the same concept is applied here on food, fully utilizing its rating.
Now the concept itself was very fun and entertaining. Just seeing food items stereotyped according to real world traits was hilarious, and the jokes/situations that ensued with it. And there were some great scenes, two in particular, which you've probably seen in the trailers.
Problem is, concept alone is not enough, and that is where this film faltered. Instead of creating creative and fun dialogue that complements the concept, Seth Rogen and the team just added crude humor, tons and tons of profanities and sexual innuendos, in order to raunch it up to the max. And while it does reel you in at the start with the novelty of a 3D animated movie with an R-rating, it all just gets old really fast. Just because the food is saying 'Fuck' for like 200th time doesn't make it more funny. To top it off, the last 10-15 mins of the movie just got too gross and overboard. It was some shocking stuff. O_O
Anyway, really missed opportunity I would say. They could done a lot more with the concept. Some great scenes aside, and the aforementioned concept hilarity, it's nothing special.
