20 years ago, a promise was made. What type of adults have they become? Did they become who they wanted to be? In 1997, they faced a huge enemy that only young courage could fight against as a weapon; in 2017 they are faced with even more formidable opponents.
Cast & Credits
It shows the lives of the characters 20 years on, the current state of Makuhara, and what happens [insert spoiler] when they meet up once more.
I would definitely recommend to those who enjoyed the drama, for nostalgia's sake, it's just so awesome to see them reprise their own (young) characters 20 years on.
They definitely did not go the expected way and just add [spoiler in comments] to the series, which makes me hope that they'll do another in 20 years ;), but it's still worth a watch.
If this was a separate entity, I probably would not have enjoyed it as much, but I did like it.
There's not much to comment on as a review as if you liked the series, you will probably want to watch it, as an add on to the end of the series, whereas if you haven't watched it, it probably won't make as much sense.
