I have read a few negative reviews of this show, and I had to say something. This is soapie gold. Now let me qualify that. If you love giant robots, sword fights and a 2D storyline, look elsewhere. If you want to watch young people going through emotional wringers in improbable but interesting story lines, get this anime.
I like anime soaps, and this one is one of my three favourite, one of the others being the follow-on series Onegai Twins. I do not understand why there are so many negative reviews of what is, when it comes down to it, a very fun show. Many people have said it moves too slowly, which I disagree with. Over thirteen episodes it covers a lot of ground, and I would have liked to have seen a lot more. The occasional slowness is simply very good pacing. Some have been critical of the implausible nature of the show, but we are talking about an art form that ignores every law of physics known to science. Others have said it is simply derivative, as if none of their preferred shows are. But bickering about these things is beside the point. Fact is you like it or you don't.
It uses stereotypes, but it does it quite well. It has a solid story that I find touching. The animation is good and the music... well... no worse than other anime. It may not be totally original, but nothing is. It does what it does with an elan that is quite rare.
And I like it. A lot.
