At the beginning audience were already given gorgeous setting and spectacular level of details. My eyes literally pleased on every single scenes I saw. The plot twist was also quite surprising, knowing that turns out the whole Itomori town was vanished due to comet/meteor impact. Then everything goes a bit sci-fi (One scene reminds me to Interstellar, idk why). After Taki know about the truth of Mitsuha existence, this is actually when the story get interesting imo. The plot is building up until the climax reached to the moment where they met for the first time in the top of the mountain (damn the scenery is gorgeous), then Mitsuha begin her plan to save the town and as the result some of them survived (and literally change the fate of entire Itomori people live there). Then the story jumps 5 years after the incident and finally Taki and Mitsuha met again. And it end happily ever after...
My conclusion is that I liked this movie. A unique idea to combined sci-fi tropes (time difference/leap, body switch, nature phenomenon) with elements of romance. All executions are done nicely and neat. The animation were great, especially the ritual dance and in some scenes for example when Mitsuha running out from the forest to get in time for evacuation. I really like the cityscapes being portrayed. You can see even the smallest detail were drawn and it is exquisite to say the least. The whole characters are also likeable. Nice performance from the seiyuus as well. And then, finally we get proper (almost?) happy ending that the couple met again in the future. There is also fascinating explanation about Japanese belief and philosophy about relationship and human bonding, which is cleverly putted and connected to the main plot.
However, I felt that Kimi no Na Wa isn't emotionally deep as 5 Centimeter Per Second, which in my case still being the best Makoto Shinkai's work until now. (Also still get traumatized from that ending...) Kimi no Na Wa in the end is close to second place as my favorite Makoto Shinkai film. Can't wait to see more of his creation in the future.
Last but not least, here is one of my favorite shot taken from the movie :
I literally drooling when saw this... Then I thought "Man... that is the most detailed car I ever seen in anime... "
