A lot or a little?

The parents' guide to what's in this TV show.

Educational Value
Positive Messages

The show isn't out to teach any specific positive messages, though you could argue that it promotes curiosity and an interest in science. Johnny's sisters' penchant for testing their ideas on their brother could give older siblings iffy ideas about how to treat younger ones.

Positive Role Models & Representations

Johnny's twin sisters are geniuses (a good thing for female characters), but they put their smarts to use by experimenting on their brother without their parents' knowledge (less of a good thing...).

Violence & Scariness
Sexy Stuff

Some potty language.

Drinking, Drugs & Smoking

What parents need to know

Parents need to know that Johnny's sisters experiment on their younger brother without their parents' knowledge, which might give some older siblings mischievous ideas. There's also some potty language and cartoony physical humor.

What's the story?

Johnny Test (voiced by James Arnold Taylor) is an 11-year-old kid who likes to play air guitar and wants to impress his friends. Everything seems pretty normal ... until his sisters begin to experiment on him with the vengeance of amateur mad scientists. With Mary and Susan's help, Johnny gets powers such as the ability to travel through time or gain supernatural intelligence when he dons a pair of pants. Other experiments have silly side-effects like hairstyles that change in the blink of an eye.

Is it any good?

Surprisingly inventive and not as violent as other cartoons in this genre, JOHNNY TEST is an age-appropriate choice for kids. The only thing worth mentioning: All the experiments Johnny undergoes are unattended by adults, which allows all types of zany plots to unfold. But as long as he's in one piece by dinner time, Johnny is free to be experimented upon every day.

Talk to your kids about ...

  • Families can talk about Johnny's parents' role reversal. Hugh is a stay-at-home dad, while Lila is an extremely busy working mom. How do real families cope with sharing roles? How have these roles changed over the years?

  • Which of Johnny's powers would you most want to have? Would you be willing to go through a dangerous experiment to get a special ability?
