Absolutely, season 3 is circus bad. The first season of Captain N was without a doubt the best; with the best story lines being used. Season 2 still had some good moments; but the introduction of Game Boy really ruined a lot of episodes for me.
Let's be honest, a giant hand-held game system is'nt the best idea for a character. His voice was very annoying and he did really stupid things.
Season 3 was and still is a big time embarrassment. The half-length episodes were extremely lame and some characters were cut for some stupid reason (I'm not rewatching these episodes to tell you which ones).
The story lines were beyond idiotic and thankfully, only a few episodes were made. The series went out with a whimper; which I feel is very disrespectful to fans of the show.
