These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Adaptation Displacement: The TV series is much more famous than the series of novels it was originally based on. It's also markedly different from the original series of novels. In the books, Murdoch is much more of a Deadpan Snarker and is outright contemptuous of Brackenreid, and solves his cases through legwork and talking to people rather than any form of science. Inspector Brackenreid is depicted as an incompetent drunk who's also bigoted against the Catholic Murdoch. George Crabtree is described as having a large build and is a married father of five.
Ensemble Darkhorse: There are many fans who are quite fond of Henry Higgins, and would very much like to see his character become part of the main cast.
Foe Yay: Some fangirls began to ship Murdoch and James Gillies together after the latter kisses the former on the mouth for a full three seconds in "Midnight Train to Kingston."
Holy Shit Quotient: Viewers all across the board were completely stunned when Gillies kisses Murdoch rather passionately in "Midnight Train to Kingston"; no one saw that coming!
The Woobie: Whenever Murdoch breaks down and is Not So Stoic, especially when Julia told him about her abortion and that it left her barren and implied that she wanted to break up their relationship.
What an Idiot: It's understandable that James Pendrick doesn't think much of Thomas Edison, given that the latter has been hounding him on suspicion that he's violating Edison's film technology patents. However, when you're an aspiring film director, it's probably not a good idea to turn down a job offer from the man who owns just about every movie screen in the United States, much less call him a "scoundrel" to his face.
