SPOILER ALERT!
I have read several reviews saying people did not like this anime. I'm sorry to hear that. One reason people were unhappy with it is the amount of nudity. Yes, I agree, it was a bit excessive at times. However, the two characters who were usually naked were Hikari and Akari, and since they had no physical form before coming to Earth, it makes sense that they would not conform to boundaries that other humans abide by (i.e. wearing clothing at all times). There were also a couple shower/tub scenes with naked girls, but in Japan, it is not uncommon for family members or close girl friends to bathe together. I mean, heck, they have public bath houses in Japan, after all. Viewers simply find it shocking because it is nowhere near common in America. In conclusion, perhaps the rating should be more like 16+, as this amount of nudity is not appropriate for a 14-year-old in the States to be seeing.
Moving on, another common complaint I saw was about the ending. No, so it didn't have a happy ending. Not everything in life is flowers in sunshine. But you know what it did have? A believable ending. I'm really not sure how it could have ended any other way. It's how it HAD to end. And it was moving. I teared up at the end when Hikari and Takeru had to be separated, especially the ending scene she saw at Takeru's house for the last time when she saw all she could have had as a human; everything she had to give up by doing what was necessary in order to save the planet she'd come to love.
Overall, it was sometimes funny, sometimes sad, always beautiful anime with likeable, believable characters who capture the viewers' attention and hearts. It did everything a good anime/show/story should do.
And so, if you are looking for a good anime, I highly recommend this one. It will stick with you.
