A short premise: I consider myself quite a romantic person, but I'm not a big fan of the "romance" genre, or rather, as I'm used to calling it, "what passes for romance these days"...^__^;
So, to give you an example, I think Kumada Rinka's "Marry Me" was a marvelous and truly romantic drama, whereas this "Manatsu no Cinderella" is just the Nth Déjà Vu Fair, (ab)using all the genre's clichés and then some (seriously, 5' into the last episode I thought to myself "The only thing missing is someone running desperately"...and bang! few minutes later, check! we got to see that one as well...), with the last straw being the ultra-lame dialogues (now, not every writer can be Michel Audiard, all right...but still, there's all kinds of shades between that and this....and this is just abysmally uninspiring).
Mixed performances from the cast (though if you're gonna watch it for Mori Nana, she won't let you down, I promise), a catchy-but-nothing-more-than-that OST and a pretty decent production value complete a package that doesn't get the passing grade.
