The Show's InfamyThis show is known for its lack of popularity. We will analyze the reasons why that is.
OverexposureA major reason why this series gets as much negative criticism as it does is for its overexposure on Cartoon Network and Teletoon. This show is constantly seen on both networks. This may be due to the show being very cheaply produced; it'll make a profit even with minimal ratings. This seems to be good logic—television is a business, but a lot of people wonder why they don't just air more popular cartoons with far better ratings.
Poor Choice of CharactersAn issue of paramount importance is the fact that the main character is the annoying younger sibling. Why is Johnny the main character? The show would likely be more popular if this role was filled by someone else like rational Dukey or the quirky but intelligent sisters Mary and Susan, all of whom are far more well-liked than Johnny. The series would benefit from Series Minus Series Core. Another issue is that the writes waste perfectly good characters. Whatever happened to Janet Nelson Jr.? The writers seem to try and shove Johnny into as many situations as possible, when the series would benefit without the constant wasted characters. Indeed, almost all episodes include "Johnny" in the title. In short, Johnny himself is a big turn-off for would-be fans.
Clichéd PlotsAnother problem is that the series has a lot of cliches in its plot. Many stock plots are used, and a lot of cheap parodies are done. The show even reuses its own plots. Now, remember that tropes are but instruments used in a story. A Cliché Storm can still be a good story, but the problem is that the writers overdo it.
