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.
Squick: Many episodes, such as A Tale of Two Cities and Pride and Prejudice featured the titular canine playing a heroic lead together with a human, female love interest. This lead to many, many scenes of attractive young actresses behaving in a romantic and cuddly manner to a freakin' dog!
Tear Jerker: Frankenstein (given that they follow the theme of the book, it's pretty hard not to be one.)
The scene in Dances with Dogs as Joe remembers his father pushing him on the tire swing is a bit heart wrenching.
The end of the Tale Of Two Cities episode. They keep the "it is a far, far better thing that I do, than I have ever done" line and the guy playing Sydney Carton is actually a pretty good actor. Just try not to think too hard about how he expects no one to notice that a dog has been replaced by a human man.
Joan of Arc saying goodbye to her friend before her execution.
