This movie is still great. Smooth animation with great art direction, relatable characters, and even some fun parts too. The plot still runs smoothly, and has a nice flow to it. But when it comes to comparing to Kimi No Na Wa, director Shinkai's last movie... This movie doesn't quite add up to the qualities that Kimi has. The plot is less complex compared to Kimi, because it only happens in one timeline. The emotional impact is also felt less. The story still has a hidden message about extreme weather, but I still can't spoil too much, so here's the conclusion:
Just don't expect you are watching another Kimi No Na Wa movie. So think as it were a teenage love story. Still a great tho.
