To be completely honest, I did not like this drama at all. The whole storyline of Koizora is poor and rather confusing. It's as if the author only wanted to torture the characters, thereby, making any soft-hearted viewer want to just breakdown and cry for the characters sake.

As I watched, I became so annoyed with the story that I didn't even watch the last episode. So, maybe I shouldn't be talking, but from what I read, it doesn't really get much better in the last episode.

Unlike many people are saying, in my opinion, Koizora wasn't even really all that sad, it was just ridiculous (very similar to the second season of the anime Clannad). I didn't like it at all.

My advice to anyone who wants to watch Koizora is: if you start watching it and even begin to think that it's going to be a drama that you don't want to watch, just turn it off. 'Cause it doesn't get better.

I know a lot of people really like this drama, and I don't mean to offend you, but I really don't understand why anyone would like it. It's a poor story, and quite honestly I don't find many redeeming qualities in it.

The only even remotely good thing about Koizora is that the actors can act and the music doesn't suck. Quite obviously I don't give any "re-watch value" to this drama since I couldn't even finish it, and the story was seriously a major fail.
