The Blu-ray also seems to take the more is better notion when it comes to bonus features. The 2D blu-ray set includes a DVD copy, as well as Ultraviolet and iTunes digital versions. Then, there are hours and hours worth of bonus features including weird ones like a mode where Aziz Ansari's pirate rabbit appears from time to time as you watch the movie, a sing-along mode, and a featurette where you can dance as characters sing (and watch some music videos). There are also deleted scenes (unfinished ones) and behind the scenes pieces which go into the sloth family, the creation of the pirate crew, Scrat, and the science (and myths) behind the film. Some of these are slightly interesting, but it's a lot to go through for minimal return.
Ice Age: Continental Drift, according to IMDb, took in more than 800 million dollars worldwide which means that we should all expect to see a fifth entry in the series pop up in a few years. Wait for that one, this one just isn't worth it.
