So other than my initial reaction (Woah), here are my thoughts.
Despite what people might think now the first Matrix was insanely amazing and influential when it arrived. It was, for lack of a better phrase, the Citizen Kane of wire-fu in the western mainstream cinema; by which I mean that its influence is so pervasive that it is difficult to understand how groundbreaking it was at the time.
The second was good, the third ... a disappointment. That said, I have found everything the Wachowski sisters have done to be, at a minimum, interesting and visually arresting. V for Vendetta, Speed Racer, Cloud Atlas, Jupiter Ascending, and Sense8 ... none of them were perfect, but all of them were great because of their imperfections, because they tried and (sometimes) failed.
I am looking forward to this. If nothing else, it will be ... something.
