True. It's more of a medium distinction than anything, and still has some distinctions that set it apart from other mediums.
For instance, last month we had a bunch of people over and watched all three Appleseed films - Appleseed, Appleseed Ex Machina and Appleseed Alpha. The second is a sequel to the first, and the third is a prequel/reboot. It was also a painfully American film; it had the same director as the first but a lot of the staff, including Executive Producer, had changed in the intervening, what, ten years. (Ex Machina was produced by John Woo, and it shows.) While visually it was evolving along lines that could be traced back to the original films and slightly more recent efforts like Final Fantasy VII: Advent Children, its plot was pure mindless American blockbuster. Going in expecting the former and getting the latter was jarring, and the other way around can be just as disorienting.
Edit: (Oh, and under the guise of recommendations: The first two are great, skip the reboot. Genre: sci-fi, utopia built after a cataclysmic world war, big mechs, biomechanical humans and obligatory moral "How human are they," quandaries, and military action.)
