Didn't like One Last Kill at all.
Part of the issue is it's like half a story. You can tell Berenthal really wanted a feature-length, mid-budget movie, but they kept him on a short leash in terms of budget, so we get half a movie instead. There's just not enough connective tissue here to make the story work. It doesn't even use the time it had particularly well, spending way too much time in the opening act (if you can call it that) focusing on Frank's hallucinations and suicidal ideation.
I'm a bit confused about where this fits within the universe where Daredevil: Born Again exists. Under Kingpin, NYC seemed like a police state, but here, it seems like lawless anarchy which seems very anachronistic, given NYC hasn't looked anything like this in 30 years. I know - you kind of need this for The Punisher, but still, doesn't fit into the MCU canon any longer either.
The whole setup of Ma Gnucci setting a particular time for the entire neighborhood to go wild was dumb as shit. I guess I can buy that it's too much of a risk for her bodyguard to shoot him then and there, even with him unarmed. But why give him a warning? So the story can take place! Why does the whole neighborhood descend into general riots and mayhem! To create a spectacle!
But my biggest issue is just this - Frank starts the story wanting to die, and then he finds out assassins are coming for him. Okay, why does he fight back? I guess we're supposed to believe that he's being driven forward on the idea of vengeance/finishing the job by offing Ma Gnucci until he decides that no, he'll be a hero instead. The final turn worked, but the reason he was fighting back so hard? I just didn't get it.
