It’s hard to believe that Ray Romano, John Leguizamo, Denis Leary, and the animals they voice are on their fifth feature-length lap with the Ice Age series – that’s a long time for any franchise.  Then again, there’s always going to be a crowd for these adventurous, likeable mammals because Blue Sky Studios knows how to make a slick-and-quick movie for families.  Ice Age: Collision Course is no different.
