Barry's humble and altruistic nature makes him an easy hero to root for, especially when it comes to his lifelong quest to prove his father's innocence in the death of Barry's mom. The line between right and wrong is clear along the superhero storyline, but a few supporting characters' uncertain motives keep viewers guessing as to their real motives. Honesty, compassion, and selflessness are considered positive attributes, even though Barry's forced to keep his identity a secret even from those close to him.
Many sequences feature violence of both the traditional kind (gunfire, fistfights, muggings, and so on) and the superhero variety, which yields less blood and injury. The Flash's weapon is his speed, and he uses it to disrupt villains' plans more often than he physically harms them. Sometimes dead bodies are shown, particularly in flashbacks to Barry's childhood and his mother's death. Guns appear infrequently, but are generally used against supernatural enemies (such as giant rampaging monsters) rather than people.
There are romantic relationships between adults, including kissing and implied sexual contact. Characters are shown in bed together but no nudity.
Occasionally "hell." Characters may use insulting language, calling each other such things as "lazy" or "sloppy."
A crossover storyline involving Arrow may entice viewers to check out that CW show if they haven't already. The Flash is a character from DC Comics and is featured on many forms of merchandise.
