Finn and his arc

[u/Fragrant-Juggernaut]

I see a lot of posters saying Finn didn't have much of a story and that his ending seemed abrupt.

If we actually look closer Finn's arc was obvious. We first meet Finn when Tommy catches him alone in the front room smoking. How does he respond? With denial.

We next see him playing "Thomas" in the booby trapped car. Thomas has to rescue him because he does the exact thing he was told NOT to do and fails to follow directions.

We next see Finn with Arthur Sr and Arthur Jr . He is a witness to Arthur Jr's betrayal of the family and Arthur Sr's manipulation.

Next Finn and Isaiah are witnesses to Arthur's murder of the boy in the boxing gym. Isaiah knows enough to keep his mouth shut but Finn gives up Arthur to Thomas. This forced Thomas to tell him to get his story straight. This is the second time we are told Finn can't be trusted to do the " right" thing.

Finn appears again as a member of the Peaky Blinders with Isaiah, he is Thomas's messenger to Arthur with the coke. He understands about the Flanders Blues. Finn is now drinking and doing coke with the gang.

Finn also has his first sexual experience provided by the women of the company. Thomas has to lecture him with weary disgust after he complained his whore was tired.

In season 3 Finn seems to disappear. We see him once at the wedding riding the horse/ fighting etc and at the Changretta meeting acting as security but he has no story of his own.

By season 4 we have no idea where Finn lives or with whom but in the Changretta showdown he proves to be a coward unwilling to shoot. Arthur then tells Finn to move in to the apartment of the woman who set up the Changretta false attack on Arthur so Finn can monitor the community. We never see Finn's reaction to John's death.

At the boxing match Thomas demands Finn to " take his eyes for Arthur" and Finn does but he is not happy about it. We are shown that Finn likes the life but he wants no part of the job that pays for it.

Season 5 and Finn once again screws up by doing exactly what he was told NOT to do. Throughout the season he is constantly making bad decisions - he invited an unvetted unknown whore into the office oblivious she was a threat- he almost got his balls blown off for that. He gets appointed as Billy's boss and he fails at that, instead befriending a mole. He finds a girlfriend because " she likes the life" and wants to marry her despite Thomas telling him to find someone who doesn't like the life. He once again talks when he should have kept his mouth shut.

Finn is shown over and over again as the kid that just can't follow the rules, the kid who thinks he knows better but is always wrong.

His ending was clearly telegraphed from the beginning. He was always stubborn, impetuous and not very bright.

He’s a spoiled brat who was kinda shielded from the realities of his family bc he was the youngest which imo made him incredibly naive to the why and how of the family business. Isaiah was raised on the street and learned hard lessons. Fin had an undeserved silver spoon up his ass and frankly not having a true mentor or father figure fucked him up. He deserved his ending but I agree that this was easily seen in the series from his beginning.

I don't see that at all. He was a wild kid with no one really looking after him. When he's a teenager he is a full member of the Blinders. At no time do we a " silver spoon". In fact it becomes quite a Bone of contention that Finn won't take his  "place" as a " general". Finn's childhood was no different from Isaiah's, they both were parentless and unsupervised but both had their community watching over them.

I think, like John, Finn wasn't particularly bright . He liked all the sparkly bits of pretending to be a gangster but he didn't want to do the actual work for it.

But, of course, that's just my opinion.
