I have been in the mood for something something ultra-sweet recently and after searching around, this fit the bill perfectly. It is just pure, unadulterated warm fuzzy feelings. Yeah, it’s tropey as hell and the plot doesn’t hold up to much scrutiny, but that’s not the point. Just sit back and enjoy the ultra-concentrated romance.
I haven’t watched I Want to Eat Your Pancreas either, so I can’t directly compare the two. I think Look Back was touching for sure, but I wouldn’t go so far as to say it reached the top tier of emotional anime movies for me. I ended up not needing my box of tissues for example.
By comparison, when I want to watch something like Tale of the Princess Kaguya, I prepare a fresh box of tissues and go ahead and clear my schedule for the whole weekend. That movie destroys me when I watch it.
