I watched My Little Monster and S1 of Tokyo Ghoul. I liked MLM; I didn't think it was really outstanding but it was pretty good for a high school rom-com.
Tokyo Ghoul was a huge disappointment. Kind of an all-around failure.The protagonist was the standard bland, spineless shonen protag, while no one else gets fleshed out enough for you to care. The show keeps pretending that it's exploring the issue of whether ghouls have a right to hunt humans to live, but in reality it sidesteps that at every turn by making every ghoul that hunts humans a sadist. No one just hunts quickly and quietly once a month, so the issue never really gets discussed. At best it's a bait-and-switch, saying up "it's just to survive" but then showing a bunch of mass-murderers and torturers. And to be clear, it's not the characters doing this (that could be an interesting commentary) but the show itself.
The other potential issue, whether the investigators are justified in killing ghouls, gets similarly side-stepped by making them also sadistic. So now it's nearly impossible to think about which side is right because the individual people on each side either are terrible, or are actively defending terrible people.
Rambling about the ending
The ending is the worst part of the whole show. It really wasn't that violent up to this point, so I don't know why they suddenly felt the need for like 15 mins of screen time dedicated to serious torture. Maybe that time would have better spent resolving any of the dozen or so plot threads and characters that never went anywhere. When episode 12 ended I was flabbergasted that there wasn't another.
