The first four Ice Ages were about Manny (Ray Romano), Sid (John Leguizamo) and Diego (Denis Leary) surviving nature and whatever it manages to throw at them. They've deviated a little or in other words, have become a larger family which in turn has increased the number of cast members. There is Manny's wife Ellie (Queen Latifah), the one-eyed weasel Buck (Simon Pegg) and Diego's wife Shira (Jennifer Lopez) who later became a part of the franchise and to introduce someone new to this film, they've got in the now grown up daughter of Manny and Ellie, Peaches (Keke Palmer) and her fiance Julian (Adam DeVine).
Just like its predecessors, all is well in the ice lands where the group is put. Mammoth Manny and Ellie's daughter Peaches is all set to get into wedlock with her fiance Julian when a series of incidents, courtesy the squirrel Scrat (Chris Wedge) who is still trying to get hold of his acorn, causes several asteroids en route of collision with Earth. With the entire clan now in trouble, they try to do what all it takes to survive and in due course, come across the witty weasel Buck who is being followed by a family of flying dinosaurs. How will they save the planet from extinction and if the young couple get together at the end forms the crux of Ice Age: Collision Course.
Though the franchise concentrates on one catastrophic event or the other in ever film, the main motive has been to make the characters fall in love/understand their family and its members all over again and Ice Age: Collision Course does the same too. Apart from the fact that now its asteroids threatening our favourite clan, the rest of the story is pretty obvious. In short, its just old wine in yet another new bottle. The main storyline rarely gets our attention and the parallel track of Scrat, as usual, saves us with some amusing actions.
Not sure if it's the repetitive story or the fact that the franchise's run has been on for quite a while, the main characters do very little to entertain. In fact, apart from Scrat, its the supporting characters that provide us the constant comic relief. Wanda Sykes as 'Granny' sloth is one such character and not to mention, Buck's alter-ego, Neil deBuck Weasel voiced by the real life astrophysicist, Neil deGrasse Tyson. But thanks to the fact that the characters that deserve screen space are one too many, the ones that actually works rarely grace the screens.
The humor quotient isn't satisfactory nor sufficient. The plot is very obvious and it's apparent on how the film is going to end. Ice Age: Collision Course, with very few positive points and a truck load of flaws, is a perfect example of what a franchise can become if it tries to rake in the bucks way past its expiry date.
Overall, considering how the dinosaurs went extinct, its high time this film franchise did the same too
