I´m watching on netflix, so I haven´t watched the whole series. What I can say so far (after 4 seasons): it is like a soap opera, in which you get attached to the characters and want to see what happens to them, you will root for some couples, be annoyed with others, and get mad with some of them. In the beggining, it is very interesting, mostly because of the topic about the foster system and the family formation. I just think that they exagerated a bit with the "important issues" and the story gets a little artificial. I understand that it is important to talk about some matters, and the show does it in a really gentle and sensitive way, but sometimes it just seems like too much; it becomes hard to believe that EVERY TIME something really problematic is happening with a group of teenagers. But anyway, it is a sweet show that got my attention and I think it can bring important information as well.
