Neither are elite, but they're fun and you should go with my recs.

The reveal would've been better if there had been some innocuous reason for Mare to go in the shed and see the box with the gun in it, then put it all together. The old man calling her to say that things 'went missing, then came back' was just lazy writing.

Overall it was a decent whodunit. The Killing was a little better, I thought, but this was good. They had no shortage of suspects, that's for sure. At one point I even thought the Guy Pearce character might have done it.

especially as he is what i presume an ex cop himself ? maybe hes being portrayed as a little senile or something, but still the way he just randomly calls her and doesnt even think to check his own cctv ....i agree lazy writing
but overall good series good acting anyways.

edit : i also thought to myself after 1/2 ffs its guy pearce who did it , they never cast big names in roles unless they are the killer glad they didnt do that.

Guy Pearce was never cast for the role. Something happened with main character cast for that rule when coronavirus started and Kate Winslet is really good friends with him and asked him to do it as a favor. I also thought he must have been involved somehow until I heard a podcast with that info.

Also, maybe I missed something and too lazy to re-watch. Did love the show. But the senile man said he noticed the gun was missing. How? The kid took it a midnight and then they put it back that night before he ever woke up. Does he check his gun in the middle of the night? Doesn't make sense.

Yeah they said he went to go check it THAT VERY NIGHT because of the prowler. Then didn't mention it for 8 months or whatever, then despite his senility remembered it exactly but not enough to check his CCTV? Extremely bad writing. It was missing bullets!

Absolutely astounding they went with DOUBLE FALSE CONFESSIONS. Why'd the alcoholic brother confess again, under this theory? Did he know the truth?

How do they not run ballistics on John's gun?

Yeah Fly's point about the missing bullets is even more bizarre. The gun is a revolver so the only way you'd even know the bullets are spent is if you dumped the cylinder, but why would the old man even do that? To me you'd find the gun, crack the cylinder, see all the chambers are still full and then be like 'huhh' and put it back in its box.

Meanwhile if the chambers were totally empty what's the theory then? That the kid kills the girl and then removes the spent shell casings before putting the gun back, but now with two empty chambers? Craziness.

With the kid as the killer I think the motivation of the double false confessions makes sense, and wasn't a bad plot point. It was even in character for the two brothers.
What did NOT make sense from a character standpoint was the kid being the killer.
Nothing in his arc suggested he was capable of that, and even the whole story about taking the gun 'just to scare her' was nonsense too. Better would have for the kid to have been closer to age to the girl, and he has some unrequited feelings for her. He gets wind of the ambush the mean kids are plotting against her so he grabs the gun to 'protect' her, gets there too late, manages to meet up with her sometime later --> confesses love --> gets rejected --> emotions go hot --> murder. Something like that.
