This "Kanojo ga Joubutsu Dekinai Riyuu" was a pretty nice surprise for me; consisting of six episodes lasting roughly thirty minutes each, it can be taken as Nth proof that quality trumps quantity (although I did find it a tad too short - more on that in a jiff, bear with me ^__-).
The story was a clean, nice, delicate one - precisely the one you'd expect from an NHK production - and that was comforting in itself. Nevertheless - and without any spoilers, I promise - the conclusion felt a bit rushed to me, so as far as I'm concerned it wouldn't have hurt to have even just one more episode so as to be able to develop it a bit more smoothly. But it's a minor detail, really - and I know I tend to be pretty picky when it comes to scripts, so take it with a grain of salt.
The cast - I'm sorry to confess, totally unknown to me - did very well, and I particularly appreciated that the dreary but alas (stereo)typical portrayal of foreigners as funny weirdos, so common in J-dramas, was mostly absent from this series. Nice one, guys! (BTW, having a burmese-born ML portraying a burmese character was also a nice touch! I wish Hollywood learned to do the same - but then again, who cares, right? I would be none the wiser even if they did, given how I'm completely detoxed from their productions anyway, LOL).
Music and production value might not be top-notch, I'll admit, and that's why I'm not rating this as a perfect 10. But it got really close, and I can wholeheartedly recommend it! ^___-
