The show is heavy on well-intentioned (if clichéd) values: not judging a book by its cover, listening to your heart to do the right thing, always giving your all to every endeavor, etc. Though the series can be pretty violent, the rangers always use their skills to subdue (rather than harm) their enemies, and they exhibit self-control, never allowing their emotions to push things too far. The multicultural cast includes a strong female and an African-American character.
Lots of fistfights, knives, explosions, and shoot 'em ups (it is a law enforcement show, after all), but the rangers mostly rely on their martial arts skills to subdue the criminals. Tame compared to current procedural crime dramas.
Some mild flirting between two main characters (which in later seasons develops into a relationship). Content sometimes touches on issues like teen pregnancy.
"Damn" and "hell" are used sparingly.
Drinking, Drugs & Smoking
Supporting characters occasionally smoke or drink. Some storylines touch on drug use, but it's alluded to rather than shown, and the drugs are usually some kind of generic, powdery white substance in clear plastic bags.
