10/10 For the story, initially it takes a bit of the time for the story to pick up pace, but once it does, it keeps you thoroughly entertained. There is a nice and slow buildup, a great plot twist in the middle and a superb ending that makes this anime one of the best in recent memory
The sound was well orchestrated depending on the mood of the scenes, but besides providing a good base, it doesn't really stand out. It doesn't make the scenes feel bette,r but neither does it make it worse. So the music gets a 6/10 in my book.
the voice acting, it was superb.The voice actors for Okabe, Makise and Mayuri in particular really gave a lot of feeling to their characters, so a 10/10 for me.
Considering both music and voice acting, sound gets an 8/10
All of the characters were fleshed out well enough for us to genuinely care about them. The slow start to the series certainly helped to focus more on the characters and less on the plot and as a result the characters all seem real rather than just generic anime characters.
Enjoyment: I enjoyed every second of it and is easily one of my top 5 anime.10/10 and a must watch in my book.
