Don't be fooled by the cute trailer.
This series is MUCH deeper than it looks. it touches on a very wide variety of topics, including some very difficult ones, and it handles them very well.
My compliments to the writers because this series of interweaving plots had to be handled very carefully and they did an excellent job.
I gave the series a lower rewatch score because it isn't one I'll watch again myself. Several of the storylines hit home a bit too hard for me, I even had to take breaks while watching the show to collect my thoughts. But only very well written stories can have that kind of impact on us, in my opinion.

The acting is quite good, a few misfires in some ways, but not enough to impact the over all quality of the cast.

The music rarely got my attention other than the theme. So it wasn't a distraction or pulling focus from the show and I consider that a good thing.

Special effects were cartoonish at times but in a way that would suit the situation. No downsides to them once you got used to them. It was a tad jarring at first but it makes sense in the long run.

Overall, this series could be a hard watch for some people with a more personal connection to some of the plotlines, but it is still a very good series and I'm glad I watched it.
