Jul 9, 2019Decent Start
Johnny Test’s first season compared to the rest of the show is actually pretty good. -
Aug 29, 2011The humour is childish and the stories are stereotypical. If you want to watch a good show from Cartoon Network, try Regular Show or Adventure Time.

Jun 12, 2011i don't like this show. i hate t.v. in general these days. bad sitcoms for 4 yearr olds, and prissy girls who think that a broken nail is a problem. cartoons that have horrible jokes. and what has happened to the old days? and this show is a rip-off of phinius and **** which is a rip-off of jimmy neutron, which is a rip off of dexters labratory. B.S.

Apr 27, 2012This is one of CN's worst shows on the channel. nothing can save this miserable pile of ****. all the plot's are very predictible and weak. the character's are just unlikable and annoying along with very predictible and unfunny jokes. In other words, skip this show and when it's on,change the channel.
Final score: F- -
Apr 27, 2013It's Dexter's Lab meets Fairly Odd Parents which you would think would be a winning combination but instead results in an abomination. The humor is beyond childish, the characters are annoying and are nowhere near likable, the writing varies from "meh" to terrible and the animation is so stiff it makes paper mario look like Disney's Fantasia!

Jul 26, 2012this show is so underrated. i don't get why people don't like it. i think it's funny and interesting. i prefer the old theme song but still it is a cool show. i kinda wish sometimes the kids would act more normal for once, but still a good show.

Feb 19, 2016Just take the Fairly OddParents and Dexter's Laboratory and combine them together and add some dumb stereotypes kids would most likely love to see and hear. You get Johnny Test.

Jun 24, 2015When this show was on Cartoon Network it was horrible.
Same recycled formula every episode no verity what so ever same jokes every episode.
Went on for far too long. Thank god the nightmare is over -
Nov 21, 2021An arguably great start to the series as a whole, and is by far the only good season of this mediocre series.
