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.
Accidental Innuendo: In Season One, Sophie wears some new red shoes which Paul states remind him of Dorothy's. Sophie doesn't get straight away that he means Dorothy from The Wizard Of Oz, and explains her confusion by saying, "You said Dorothy like she was a friend of yours". Paul's face is nothing short of priceless for those who know that "a friend of Dorothy" is a euphemism for being gay.
Adaptation Displacement: The original Israeli show it's based on is one of the most successful shows in Israel, and its first season is identical down to almost every single shot. However, it may be canceled because the lead actor tried to kill his wife, so that the third season will definitely be new material.
Alternative Character Interpretation: The general concensus seems to be that Alex was gay. This is never confirmed by Word of God so alternately he could really have just been seeking the solace of a community that wasn't so oppressive, wasn't trying so hard to nail him down into a rigidly conceived box, wasn't so heavily leaning on him to excel. Considering the way his father treated him... not to mention the military mentality.
As an example in one of his later appearances he tells Paul about a dream with supposed homosexual imagery, in which he expresses his desire to "shove an air to air missile up the rear burner" of a fleeing pilot. While homoerotic subtext can easily be read here- the dream itself is very reminiscent of an incident he relays to Paul immediately thereafter, about his wife's attempt to take him back to a hotel... and hopefully afterwards convince him to go back to active duty again. He avoids and it doesn't happen. He even says "she's on a mission". It's possible that he is angry at himself for failing to live up to his responsibilities. He also accepts the logic behind concluding that he was homosexual, admitting that it would explain a lot, which doesn't seem in keeping with a closeted individual.
"Mom, when I grow up I want to be a rock star!". "Oh, honey, you know you can't do both..."
Oliver's turtle crawling out after he leaves, long after Paul and probably much of the audience has forgotten about it.
The Scrappy: Virtually everyone who watches the show hates Laura, Jake, and Amy from their first episodes. To be fair, the other characters aren't too pleasant either, and everyone is a Jerkass at times.
The Woobie: Most of the patients, but especially Sophie and April.
