YMMV: The Girl Who Leapt Through Time
Adaptation Displacement: It's an "adaptation" of a Japanese novel that it's actually more of a loosely-connected sequel to. Notably, the author of the original work loved this movie and said that it was perfect as a "unique sequel."
Crowning Music of Awesome: "Kawaranai Mono" by Hanako Oku—played when Makoto realizes she has one time leap left and knows she can help Chiaki. She rushes out of her house and makes three leaps as she heads back in time while seeing memories of when Kousuke and she first met Chiaki and developed their friendship.
Especially when Makoto starts crying herself. Good grief.
For those watching the DVD, the included music video for the song "Garnet" can be this, especially if watching and listening while reading the subtitles.
I'll burn the days that I spent with you into my heart
So that I'll be all right even if I don't remember them
Even if I fall in love with someone else someday
You will always be precious and important to me
And this season will come around again
Shocking Swerve: Well, to several viewers/reviewers at any rate, the last forty minutes were just slightly out of left field. Up until that point, it followed pretty much every convention of a girl's coming-of-age anime, until Chiaki reveals he's from the future. When you're expecting the typically-unexplained magic power that ends in a lesson about responsibility and with status quo being God, it's a bit unexpected.
Values Dissonance: A number of Japanese reviewers on Amazon HATE Makoto for swapping in her classmate in home ec and making him the target of bullies, thereby probably dooming him for life. And not even feeling sorry for it or trying to change it (although presumably it is undone along with all of her other changes during the final time leap). This point, along with her eliminating her friend's relationship with Chiaki, is almost never brought up by Western audiences.
Because Chiaki steps in front of Makoto to shield her from an incoming fire extingusher and gets injured, Makoto uses a time leap to push him out of the way. However, this time around it's Yuri who gets injured.
