The reviews of this anime are all over the place, going from a solid 9 down to a 3 and back and forth. While many criticize this i really enjoyed my time watching it. But it wasn't really a show i was itching to finish, the only time i felt excited like i had to go watch the next episode was near the end when things were tense. That being said, it's a really good anime.
The characters are lovely. I like their dynamic, the obsessed stalker and the emotional teenage boy. It's nothing new, this dynamic is not uncommon in anime, but they way it was done here was, at some points, thrilling and gut wrenching. Not knowing whether or not to trust Yuno was a full on rollercoaster. And the other diary holders were quite the characters, I even started to feel for them and root for them a little. I really liked the couple and ninth. Even the characters that weren't diary holders were memorable.
I'm a big fan of the art and the animation, especially in the last episode, the animation was so fluid, fun and thrilling! I'm a big fan of the 2000s-early 2010s anime art anyway but the art in The Future Diary particularly is phenomenal. Plus boobs.
All in all i could see myself rewatching this and i really did have a good time with it. It's definitely missing some elements and it did drag a few times but it was still a fun watch.
