Ice Age: Continental Drift

Ice Age: Continental Drift is a 2012 3D computer animated comedy action film directed by Steve Martino and Mike Thurmeier. It's the fourth installment of the Ice Age franchise.

Why it's underrated

 * Excellent humor, like the previous Ice Age movies.
 * Great animation, a big improvement over the already great animation of the previous three movies.
 * The story, even though a bit absurd due to the fact that was caused by Scrat, is decent and it's actually compelling and interesting with a fast rhytme.
 * The characters, especially Manny, are still likeable, mantaining the charm they had in the first three movies. The Pirates, Louis and Granny are also well written characters and great addictions to the franchise.
 * The voice casting is really good, thanks to all the voice cast of the previous movies reprising their roles and new addictions like Peter Dinklage as Gutt.
 * Well executed action scenes, like the scene where they steal the ship from the Pirates or the Sirens scene.
 * It brought new elements to the franchise and furthermore explored very well the Ice Age world.

Bad Qualities

 * The subplot of the Teen Mammoths can be a bit boring and the inclusion of Drake and Nicki Minaj felt unnecessary due to the fact their characters barely have an important role in the movie.
