The Ice Age franchise has been around for 20 years, becoming one of the most popular animated series, yet looking at the Ice Age movies ranked can make it difficult to find the best. The franchise managed to amass an impressive total of $3.2 billion at the box office (via Forbes), even if the quality of the Ice Age movies varies significantly over the six installments released so far. At its height, Ice Age was a wonderful family-friendly adventure with memorable characters. At its lowest, it was a disappointing recycling of ideas with a franchise that wore out its welcome.
