Is that blood all over the cockpit? ewww. :eek:
If you had done this 3yrs ago you wouldn’t have to worry about the fighters. 
What kind of laws of physics allow that thing to fly? Pretty, but seems implausible…
It Glides and stuff. 
Yes, she woke up!!! 
OK, I’m confused. So was waking her up a good thing? And what was up with the tower?
She had to tell Hiroki she loved him, awwwwwwwwww. 
It is a film that gets better each time but yes it was good because who wants to be trapped in a coma.
The tower was a very large scale version of the experiment they were doing earlier to bring in a parallel reality. It was designed by Sayori’s grandpa so we assume that somehow when she was younger there was some sort of connection made between her and the tower. That is why she always saw the vision and had the dreams which were the parallel realities being manifested in her mind rather than the real world. That is why the 20 km radius around the tower was empty. While she was asleep the field wasn’t growing and that is why Takuya and the others wanted to keep her under. They were worried that it would eventually continue to envelope the whole planet. I think with the war starting they had the chance to blow the tower up and it would believed a act of war or terrorism. That way after Sayuri woke up destroying the tower would sever the connection and leave her and Hiroki to get it on. Snoogins!
Then I assume that there was a psychic connection (or you could call it love maybe) between Hiroki and Sayuri and that is why he saw her in the hospital and they touched hands I believe their souls connected.
That was my take. Let me know if it helps or I missed something. Great film overall!
Having never been in one, I can’t really say I have an informed opinion on that. 
That makes as much sense as anything I could get out of it. I think I might have to watch this one again.
