9 TV Characters Who Randomly Changed Personalities

3. Sherlock Holmes - Sherlock

It's no hot take to claim that Sherlock completely crumbled after its stellar first two seasons, and that's partly down to how the central detective's personality became almost a parody of what people thought Sherlock Holmes was.

Sure, he was always arrogant, self-centred, and a bit of a s***t, but these traits were balanced by him being vulnerable and most importantly, human. Despite struggling with emotion and having an IQ bigger than the ratings the show pulled in for BBC, he still had flaws, and he still felt like someone who could exist in reality.

By the time Season 4 rolled around though, Sherlock was pretty much a superhero. Not only was he indestructible, but he was so smart that most of the actual detective work was done off screen, or in his mind palace where the answer was so obvious to everyone but him. He won by default, with the rest of his personality defined by quirky antics that negated the need for the writers to actually give him a personality.

The entire point of a Sherlock show is in the deductions and figuring out a case, an element which defined the series' earlier years, but was replaced by arrogant mugging, and the character always being correct about everything after resorting to his robot mind palace. Not only did it suck the joy out of the actual show, but it made Sherlock feel more one-dimensional than ever before, as all his human elements fell to the wayside.
