The best way to summarize Sola is to say that it's a great concept, poorly executed. The story is awesome. Really awesome. Not since Kanon have I seen a story so semi-tragic and bittersweet. However, the art is terrible, and the voice acting is subpar. The way the story unfolds definitely could have been done better, and except for the song "Binkan Na Fuukei" by Ceui, the soundtrack is unexceptional. However, the story was so great I quite enjoyed it anyway.
