Koizora is AMAZING! I loved the movie! It's one of my all time favorites and it's very romantic in every way! The general tendency is to believe that romance is sweet and good as a definition but romance has two sides - Locus amoenus and locus horrendus. The romantic side most relate to is the locus amoenus - the good and sweet side. Koizora is a mixture of both in parts albeit in my opinion the locus horrendus is more often than not present in the movie through the atmosphere rather than actual scenes! It is a brilliant movie, well performed with a solid story line that captivates the audience! The other two I have yet to watch...someday maybe! :)
