I didn't watch the second season immediately after watching the first. I like to give a break because then I feel I am able to enjoy the characters better without getting tired of it. I prefer this part of the story than the first. By this time, the build up phase is over and we are well acquainted with the characters. Finally I grew to love Makino's character. I wasn't a fan of hers in the first one because I had a hard time understanding her. But she improved this time around. Her feelings and actions were clearer to me. I was very happy with the characterizations of each character. I loved F4 and the best character was that of Domyouji. He really grew a lot. Also, there was enough emphasis on Akira, Rui, Soujiroh and Yuki. The characters of Hana Yori Dango are all very captivating. This season kept me hooked till about the last few episodes. By then the breaking-up/getting back together thing tired me. And the amnesia plot was ridiculous. Other than that, it was written wonderfully. The direction and execution of the show were also wonderful. The ending was also good. I believe it has a decent rewatch value. And since the first was a 10 according to me, this one deserves a strong 10 also. So if you liked the first season, then definitely watch the second.
