In my very humble opinion, Japan produces every year (and even more so did in the past) a very decent number of good to great manga. It is therefore quite frustrating, to this humble reviewer, to constantly see how so many dramas decide instead to adapt a manga which doesn't belong to the aforementioned "good to great" category, but rather to the "meh to nope" one, as is the case of this "WataOji".
A bunch of tremendously immature adults who keep acting in a tremendously immature way 99% of the time for what is supposed to be "comedic effect" but instead ends up being just embarassangly annoying - as I always put it in such cases: ridiculous rather than hilarious.
The other 1% of the time, the script pretends to go deeper but again fails miserably, resulting instead in an awful "going through the motions of getting deeper, all while remaining as shallow as your regular poodle instead".
The acting also suffered from the terribly poor script, and even actors I like (as Okada and Endou) got negatively affected - and as for the rest of the cast, sorry but they were mostly abysmal imho.
The music is the only very good thing in this drama, but that ain't of course enough to grant it a passing grade, alas.
