Over 14 years the Ice Age films have consistently been feel-good fun and have given us lovable and hilarious characters.
Scrat and Sid the Sloth have kept us coming back for more, though the franchise never quite reached the top shelf of animated family films.
But after five films the winning formula is starting to wane. There are only so many natural disasters this group of prehistoric animals can survive, and in Collision Course things go interstellar, pushing this franchise to far-fetched limits.
A lot of crazy ideas are thrown at this "defining chapter". All our old friends are back -- Manny, Sid, Diego and the rest of the herd, along with Buck, who first appeared in 2009's Ice Age: Dawn of the Dinosaurs.
