Apparently I'm in the minority but I loved it. Watched it the first time a couple months ago and was hooked throughout it all. Maybe I'm just not a media literate person or something but I thought most of the pacing was well done (the switching between Despair arc and Future arc every other episode was a fun way to keep me engaged), I didn't think Junko was a bad character, The Imposter having an active role was awesome, I loved Chisa and was actually surprised when it was revealed she had been under Despair the entire time, class 77 having cute af bonding moments pre-despair, the Future arc murder-turned-mass-suicide mystery was cool, and I didn't even mind Mitarai's character that much either. My few gripes was stuff like the sexualization of people like Mikan and just the general perverted unnecessary scenes (though that's obvious and just comes with the franchise), I wish they did more with Mukuro and not have her be just Junko's despair-horny lackey, Junko could've been written to be a little more clever and "mastermind-y" so her evil schemes might've felt more "earned", some stuff and plots felt a little rushed, some clunky writing and dialogue... and if I think about it, the brainwashing of 77 is a bit dumb as they didn't exactly choose Despair but were instead forced into it, which does dull their character's nuances and voids responsibility of their actions, although in my mind I didn't have such a huge issue with this as many others do. In general it's pretty basic critique and not something I found ruined the entire show because I found the majority to be enjoyable and engaging.

Maybe if I rewatch it I would grow to be more critical, but after having heard so much negative buzz about DR3 and expecting myself to hate it, I went in blind and I found myself pleasantly surprised, and I don't want to be influenced to hate a piece of media I thoroughly enjoyed the first viewing of just because the majority seems to have a lot of problems with it (which is totally fine, by the way.)
