As I've already said a few times, I'm a sucker for time-travel related stories, and it was therefore with pretty high expectations that I started watching this "Toki wo Kakeru Bando" - the title reminiscing of the überfamous "Girl who Leapt through Time" also had something to do with that, as well as the presence in the cast of two of my faves from the current generation of J-actresses, Ohara Yuno and Shiraishi Sei.
The script had its good moments but also some not-so-good ones. As far as I'm concerned, too little focus on the time-slip part and too much on the music - note that this "light music" (in the Japanese sense - "K-On", short for "keiongaku") ain't really my cup of tea, so there's that too (had this been about classical music, or jazz, or blues, or tango, or bossanova, or any of the dozens of musical genres I like better than pop, I think I would've like this series a lot more).
Anyway, the acting was pretty good, particularly from Ohara & Shiraishi but also from Miura.
The production value was OK, and the music objectively catchy.
All in all, not a masterpiece but still a decent series imho. 7/10
