I've finished watching Fruits Basket. It's certainly an interesting series, but I have to say that That I don't think I've ever seen a series where so many of the main and supporting characters have issues and traumas in their past. I also don't think I've seen a series where there are so many mean, annoying and downright nasty characters in the main and supporting cast.
I've seen it said that the series had a sad ending, but I didn't find it sad at all, in fact I thought it had a really good ending.
