Have seen this move n below is my honest review:
All these characters are well known to those who play the game on your devices.
Obviouly birds are good in game n here too to fight with lazy pigs.There are many characters in move. Few angry ones, few are peace makers but to get their stolen eggs all will be influenced to be angry n fight with pigs.
Finally birds will break pigs kingdom n get all their eggs back.A mighty eagle n the new born birds make us to smile n admire.See the rest in movie. enjoy
