There were many things that felt overused and dried the anime out such as Takajou over-obsessing and fawning over Misa, and I actually really used to like his character at first. A lot of the comic scenes were repeated too often for my liking. I'm also not a fan of the main character finding a lover in anime that isn't listed under the romance genre, because they most likely always give some random reason for a character to have feelings for the main character to the point that it just doesn't work and appears dull and unreasonable, and sadly a lot of anime do that. Examples being Owari no Seraph, Noragami, and Boku no Hero Academia. I'm just not a fan of forced relationships that don't develop naturally like how love should develop. It shouldn't be just some random crush out of nowhere, however, I'll let Charlotte slide because it was the ending. I still didn't see that much bonding between the two of them and her persona wasn't anything special.
The abilities that people have aren't all that creative, however, their side effects can be, and it's nice to see characters having weaknesses and how differently they use them. That didn't fail. Yuu's "hidden" ability is immensely overpowered and in the final episode they didn't leave out any good use of abilities in the world, which was lovely yet melancholic to see.
The many plot twists worked perfectly and the backstories and deaths were deeply depressing. The anime executed the time travel quite efficiently, and time travel is an easy thing to mess up. A few times, the time travel scenes didn't mention that much, while others mentioned a load. It all really depended on how much you looked into the gaps between what they repeated and what they didn't.
The anime made a drastic change to Yuu's character in episode 7, but for some reason, they decided to discontinue it like it never happened. The comet was also mentioned once and never mentioned again and the English voice acting in the sub was sub-par. The Engrish being spoken by Yuu and others was hilariously adorable though.
Yuu appears to be quite sadistic. Very sadistic. Hella sadistic, and I like it. He still feels human but that little twist of insanity that continues all the way from start to end, switching on and off, is something that I'm definitely a fan of.
The ending was... alright. Although after having him wanted by the whole world with them all trying to kill him, they never mentioned what stopped them from attacking him anymore. Everything just became normal. And what about the vaccines that they mentioned? Who did that?
Overall, it's not the best of anime out there, but it most certainly isn't the worst. With slight improvement, the anime would've been amazing.
