Sometimes I skip all reviews and just watch the drama I want to watch. In the case of Good Morning Call: Our Campus Days, I am so glad I didn't read all of the negative reviews first. I loved it WAY more than I thought I was going to! I thought the first season was ok, but the second season hooked me almost from the beginning and then on to the end. I thought the acting was better, the writing was tighter, the characters were more developed, and they were less immature than when they were in high school. I loved the addition of cutie Sugino Yosuke as Natsume and I loved seeing characters from the first season like they were old friends.
After I finished this, I read the reviews here and (slight spoiler but not really) people didn't like Natsume because he chased after Nao even though she had a boyfriend. But if you paid close attention, you could see that Natsume really didn't want to like Nao - he fought it and fought it, until he couldn't fight it any longer. That doesn't mean that he should have gotten the girl in the end - but it made his character more understandable than I think people gave him credit for.
I was rooting for Uehara and Nao to get their acts together and I think this season showed real growth for the couple. People grow up in fits and starts and none of us were fully formed humans right after we graduated high school - especially ones that basically had to raise themselves. Both Uehara and Nao showed real growth through this season, and I was here for their partnership. Both characters referenced needing to expand their worlds throughout this season - and that is often not easy. They both had to learn how to communicate better (and more often!) but that's life.
The first season was incomplete in my opinion, and that's why I like multiple seasons so much - we had more time to spend with these characters who just needed time to grow up.
