The Angry Bird Movie surprised everybody three years ago by being quite good. And, unexpectedly, the sequel is good too, which is a considerable achievement if you think that this animation is inspired by an iPhone app.
I mean, shooting flightless birds at grumpy pigs sounds clear fun, but a movie needs more than that. The creators managed to write a saleable story around the characters, and it worked well. Now the adventure continues: one day icy cannonballs hit both the pigs and the birds, coming from the mysterious Eagle Island. The birds and the pigs must stop their private war and focus on the common enemy. Their collaboration is not without difficulties, but Red must gather his old and new friends and defeat Zeta, the extravagant purple eagle who wants to occupy their territory.
