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.
YMMV: The Mousetrap
Adaptation Displacement: To some degree, anyhow. Think about it: how often do you hear anyone refer to the original short story or radio play Three Blind Mice instead of the play?
Although that's partially due to publishing of the short story being banned in its home country until the show stops running. It was, however, released in the United States.
Freud Was Right: Many viewers think that Christopher Wren is supposed to be gay, based on his mannerisms and finding Sgt. Trotter to be attractive (as a policeman), "terribly hearty", etc. Officially, he's not.
