because they love him
If they like it, no.
No, a lot of 20 year olds watch them
It is an adventurous show without being violent and their is a talking dog in it which is like many other young kids shows.
Yes you can be to old to watch some of them
There's no age limit to watching Johnny Test, anyone who thinks that Johnny Test is a ripoff either doesn't watch cartoons anymore, or they're just plain boring. Besides, if you hated it, that would be sadder and Johnny is actually more clever than Dee Dee(expressing anger about those Johnny Test haters out there). Johnny has an alter ego, asks his sisters to invent stuff for him(which is actually cute because it's not a boys vs girls theme), and it depicts what today's kids are actually like, and what our childhood lives used to be.Overall, if you want to watch Johnny Test, watch it, don't let ANYONE tell you otherwise.
Never
I think people don't like Johnny Test

Usually 5 and up, it has some bad influences that you need to teach children not to behave like. Other than that it's fine.
When they actually watch the series and actually take the time to think about what they like about the show instead of saying that it's a ripoff
Adults still have a child in them, so it depends what they like.
