Ok , I have just seen this and I am still trying to recover and take it all in.
First of all though I must warn people right now thatif they go into this film expecting GitS2 they are going to be very dissapointed. Innocence is a very different film but it also has many references to the first film, for instance the title credits begin in the same way as the first film where we see how a robot is born, but this time it is all in 3D and looks truly amazing and a HUGE advancement over its predecessor.
So what is the basic plot without spoiling the whole story? Well things begin on a crime scene and batou shows up to investigate, 3 people (including 2 police offices) have been brutally murdered by a doll/robot that has gone out of control. It turns out that only 1 certain make of doll is going awol and some of the victims are high up polititions and other important figures, all of the families never took action against the company of the dolls and its upto section 9 to figure out the truth and see if there is a terrorist action. This is all revealed after 15 minutes and of course this being an Oshii film there are many twists and revalations that unfold as the movie goes on. The other main plot point focuses on Batou's feelings and his search for Kusunagi. The plot reminded me an awful lot of the two Patlabor movies combined into one, not that that is a bad thing of course. One thing that will make a lot of people angry and confused is that half of the script is quotes of proverbs. Also I really dont think that many people will even understand 100% what is going on because of the level of the language used, people complained about the 5 minutes in Matrix Reloaded with the Architect, imagine 2 HOURS of that sort of thing for the whole film. This is a very deep and thoughtful movie with only a few key action scenes, and seeing how most of the people that will go to see this will be expecting lots of action most of those people will be very dissapointed, for example there is more time spent on Batou's basset hound than there is on lots of explosions and killing. But when the explosions and killings do happen you wont be dissapointed, they are quite simply stunning.
Now about the animation, Innocence is quite simply the greatest looking anime I have ever seen, the level of detail is mind blowing and most of the time looks almost photo realistic, AND the characters really blend into it so it all looks natural, unlike many previous anime where it was very clear the difference between the 2D sprites and the 3D backgrounds. It is simply amazing and raises the bar on what can be done with CGI in anime like the original GitS did when that was released.
Overall I have to say to say I loved Innocence, maybe even more so than the original. It is not only a fantastic sequel to an all time anime classic but also an amazing film in its own right, something that cant be said for the Matrix sequels. For a showcase of Production IG's talent and CGI in anime I dont think this can be beaten, even Studio Ghibli's new film's CGI looks a bit dated compared to this and that is not even released yet. Also the story is so deep that people will find new things in the film even after viewing it many times, it looks at so many things like why humans want to create machines in their own image and also about humankind as a species, it makes the matrix film look like a kids story. I for one will be going to see this many more times in the future and I reccomend this film to anybody that loves anime or very deep and thought-provoking films in general, as long as you dont go in thinking that this is the sequel to GitS or its going to be like the matrix films you shouldnt be dissapointed.
