These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Paranoia Agent
Alternate Character Interpretation: In the last few episodes, Lil Slugger nearly levels Tokyo. Fans disagree about whether this happened because Misae gave him a serious Reason You Suck Speech, which seemed to cause him physical pain, and may have made him flip out. or if it was just a buildup of the lies, fears, and desperation that created Lil Slugger and drew him to his victims in the first place. It basically depends on whether or not you view Lil Slugger as an actual person with thoughts, emotions, and everything, or just a force of nature acting without any real agency over its own actions, akin to a landslide or a flood.
Awesome Music: The opening theme, a cheesy, bombastic, electronic tune whose cheerfulness contrasts the show itself in an odd, yet satisfactory manner.
Hilarious in Hindsight: The series revolves around a young boy coming to those who are desparate and screwing badly with their lives and thereby rendering their previous worries mostly moot, to the point of putting them at mortal danger, who’s earned the moniker ‘Ha...’ er, ‘Bat Lad’.
Some Anvils Need to Be Dropped: If you strip away the fantastic/disturbing elements, you can take a number of these away from the series. Among them are, "Don't let lies spiral out of control", "Take responsibility for your own actions and faults", "Don't ever be afraid to face the truth", and especially, "Just because something is comforting or seems to help doesn't mean it's not destructive."
The delusional Makoto Kozuka is apprehended and suspected of being Li'l Slugger but is killed by the real one. Slugger attacks those driven into corners, and Makoto was stressed by the intense and physically abusive interrogation from Ikari - as well as the rest of his life, as implied in episode eight - to the point that he wanted to die, much like the ghosts of Zebra, Fuyubachi, and Kamome in episode eight. Unlike them, however, he gets his wish when he is bloodily beaten to death at the hands of Lil' Slugger.
Tsuki and the trainee in the episode "Mellow Maromi" also qualifiy.
Each member of the animation team could be a Jerk Ass Woobie. They were pressured to reach some deadline, and because of Lil' Slugger -by extension, themselves- they each DIED to complete the first episode of a series. However, the Jerk Ass comes from, yes, picking on the idiot of the team, and ALSO from the fact that none of them cared if the others died to complete the show, so long as the show was completed. And the ending before the "Take a rest" part... Dear lord... no wonder they all went nuts, with higher-ups like that.
Maniwa. He ends up going insane and ruining his life, but it's necessary in order to combat Lil Slugger, and in case something akin to Lil Slugger ever appears in the future.
Woolseyism: The choice to change Shonen Bat's name to "Lil' Slugger" for the English Dub; if they had gone for a more direct translation it would have been "Bat Boy," which doesn't sound quite as iconic and besides, it's already taken.
