Follow-up review from previous 1 and 2; this will be much the same - they all should be in one package, but unfortunately they are not. 3 and 4 dive deeper into a mystery and involve more depth overall.
For the curious, Arise (1 through 4 + New Movie) is a complete-sort-of prequel to the hit Anime series Ghost In The Shell: Stand Alone Complex; which is based on themes and characters presented in the original GiTS manga and later film.
It features a much younger Major Kusanagi; within a younger appearing prosthetic body (simulating for her, and the audience, a feeling of "age" or what might call it for a Cyborg).
It deals with many themes of "self" and identity throughout this mini-series, if a human were to become a cyborg could they still trust their own pysche if it were to be hacked. A larger mystery and story unfolds throughout as well with the Major the tip of the spear.
And of course it's done within a layer of Cyberpunk with an excellent OST. The packaging comes within a box - two films per dual border set. While it doesn't add truly anything groundbreaking for GiTS in particular, it IS a decent entry for Sci-Fi Anime at the very least. If you're fan, its worth collecting.
