Action sequels, like most movie sequels, tend to just rely on repetition. The best sequels, however, are those that recognize you can't just do the same thing again and go in wildly new directions. That's why "Mad Max: Fury Road" is widely considered not only one of the best sequels ever made, but one of the best movies ever, period. This is a period war action movie set on a Finnish Fury Road, and a live-action Bugs Bunny movie. From there, we get a brutal, over-the-top, balls-to-the-wall entertaining war film that's very much like "Fury Road" but with way more Soviets.
