Seriously, there are times when you watch something so tremendously satisfying, that you kinda feel bad for not being able to rate it more than "just" the top grade, and it is precisely the case with this fabulous "River, Nagarenaide yo"!
Hard to explain why it hit me so much without giving anything away (and that'd be a pity 'cause it would deprive you of the pleasure of finding out by yourselves!), I'll just say this: the premise is as interesting as they come; the way they actually made it work was nothing short of a serious stroke of genius; the technical difficulties I can only imagine but must have been something indeed, chapeau for the way they brilliantly overcame them; the cast did *marvelously*, with a special mention for the amazing, lovely, gorgeous (I could go on and on!) Fujitani Riko; the setting is simply F-A-B-U-L-O-U-S; the "packaging" absolutely top-notch (I normally am not really a fan of hand-held cameras, but there was no other way to make this work!).
What are you waiting for? Go watch this *now*! You'll thank me later! ^____-
10/10 and instant top10 of all times, as far as I'm concerned!
