But above all, what i dislike the most is what the movie does to Shizuno.
In the show, she is fully aware that the Kyo she loved (and loved her) died when he blew himself up during the attack on G-phaetus. She comes to terms with it and makes peace with Kyo 2.0 about that. Eventually gives her 'life' knowing that an AI like her has no chance of becoming human. Ironically, her surviving but free of her memories is both tragic but also a blessing, free to live a human life and able to move forward with the chance of actually becoming human, something explicitly said in the final episode.
The movie decides to ignore all of this and sticks her with the salvaged Data of Kyo 1.0, she regains her memories for some reason and decides that she won't become human and would rather stay with her Kyo. Both fuse of sorts becoming a single meta-body of sorts and decide to spend the rest of their existence in the backup server of maihama in shibuya until it breaks down This is dumb, i hate it and goes entirely against the point of the original show and feels awful for both Kyo and Shizuno.
>TLDR
It's not a good film. Too many ideas, questionable development and not enough time to explore anything. Should have been a 12 episode show at least.
