The third and last season is almost a whole new thing. The only plot continuing from season 2 is Koi and Dao's story and there's only a few familiar characters on top of that. Basically you don't need to watch the previous seasons to watch this one, which is both a pro and a con. We saw Jane in the preview so I had some kind of expectations of Jane throwing the old characters' relationships upside down. Instead, we got a new cast and new stories... nothing familiar to hold onto. These new things had to make us all fall in love again, and I have to say they did it, but not as well as the previous seasons. These three seasons have gone through every hardship a person could possibly have within a small amount of people who all are somehow connected. At some point I started to feel that this is way too unrealistic which affected my way of watching this series. It feels funny. Despite that, I appreciate that a drama would view these hardships to show what people may go through and how you can survive. You can relate to some stories, some affect your feelings and you will always want to support the characters. That's a trait that will make you watch it till the end. Hormones 3 is way better in advertising than the previous ones. The products were nicely portrayed and it wasn't made annoyingly obvious. This was a nice improvement. The cast didn't have the best acting skills. It makes you feel weird when the actor/actress just can't get it straight. Somehow I still like the cast, even though I miss the old one. Again, they left quite much open in the end, but the little surprise left a good feeling about the ending. All in all, Hormones 3 didn't meet the high expectations I had after two brilliant seasons, but it was nice addition to the drama series. I will probably rewatch only seasons 1 and 2.
