For me, it had a lot of potential, but this was dimmed by a couple of screw-ups along the way. Over-the-top drama (in the latter half; and despite the obvious attempts in inducing your tear ducts to give, it failed to make mine do so), too much deliberate withholding of information, and many times a shoddy attempt at making mystery and more fleshed out characters. Well, mostly my complaints about this show came to surface in the way they chose to bring the story to a close. By then everything just seemed so forced to me.
*minor spoiler ahead, if you can still consider such a spolier*
At the beginning I was so entranced by Taiga and Ryuji's chemistry and I couldn't wait until they got into terms with their feelings - but by the time this had happened, I couldn't really care less anymore because of the events leading to it. IMO, they bombed the last couple of episodes.
But anyway, this was a decent show. I actually finished it and I'm not a huge fan of the genre. So go on ahead, give it a try. Perhaps I just didn't like the latter half because I kinda hate overdone drama. It may float your boat though, so don't take my word for it. :)
