A huge improvement I'd say and it is about the survival of the fittest!

Rating: 7/10 (12 June 2014)

Certainly it has decent improvements in various aspects but the adventure part is not so exciting. However, the animation is beautiful and the story is definitely better so it makes up for it cause when compared to its first film, there are more details and characters are introduced in this sequel.
Last film was about three prehistoric animals and a baby; this film is about variety of herds of prehistoric animals traveling together to migrate to a safer environment to live in with several predators in the way in addition to more fun and humor. That is a huge improvement I'd say and I really liked their character designs. Probably strange but honest, I love the underlying ecological message most, which is the survival of the fittest. And oh, Scrat appears more too!
