I don't know what is going on in this thread. When I saw it, most of what I had heard about it was that it was boring and frustrating, not that it was the best movie ever, and you know what I thought when I saw it? "That was almost the best movie ever"
I was teetering on the edge of full blown tears (and I haven't ever actually cried to an anime so far in my anime career) since the end of the first section, and if there had been one single actual tragic event, I would have been absolutely sobbing. Now, all of us who saw it know that Shinkai didn't choose to take the "soap opera tragedy" route, so it ended up just being melancholy and not pound-you-in-the-heart tragic, but it still manages to give me goosebumps every time I think of it.
I'm just rather surprised that so many people didn't get it. At least we can all agree when it comes to the beautiful art...
tl;dr, it was by no means perfect, but it is still one of my favorites.
