* AdaptationDisplacement: The TV series is markedly different from the original series of novels, though as a character, Murdoch in the TV series is quite similar to the Murdoch in the novels. In the books, George Crabtree is described as having a large build and is a married father of five.
* EnsembleDarkhorse: 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.
* FoeYay: Some fangirls began to ship Murdoch and James Gillies together after [[spoiler: the latter kisses the former on the mouth for a full three seconds in "Midnight Train to Kingston."]]
* HolyShitQuotient: Viewers all across the board were completely stunned when [[spoiler:Gillies kisses Murdoch rather passionately in "Midnight Train to Kingston"]]; ''no one'' saw that coming!
* TheWoobie: Whenever Murdoch breaks down and is NotSoStoic, especially when Julia told him about [[spoiler:her abortion and that it left her barren]] and implied that she wanted to break up their relationship.
* UnfortunateImplications: In a number of episodes, [[{{Eagleland}} Americans]] are portrayed as evil bastards, especially in "Murdoch Air."
