Nozaki-kun (Crunchyroll) ended about as well as any off-the-wall comedy could end. It stayed funny through all 12 episoded and avoided the temptation to betray its premise with a sappy ending.
Of course this show is mostly about skewering the tropes of shoujo manga, so I don’t know if it would appeal to someone who is totally unfamiliar with the genre. But if you do know something about shoujo manga (whether you love it or hate it) then you probably will find it pretty funny. It’s all in good humor and even the most devoted fans of shoujo will probably be more amused than offended.
