Review for the original short (2009 or so) here: http://www.anime-planet.com/users/ForTheLoveOfLoli/reviews/12384
This near half-hour, what, sequel? makes no more sense than the original 6 minute short. The animation, comedy, voice acting and characters, let alone the plot, do not improve. In fact they have deteriorated further. To this we can add that it simply becomes boring within ten minutes - about a third of the time through. I watched animes before that made me want to demand my lost time back, or maybe kill a random person on the street out of sheer frustration. After watching this 2012 version, I feel like I am less of a man than before, and I am wondering how much life is really still worth to me.
If you value your life - do not watch.
