Courage the Cowardly Dog was a very nice re-watch, most folks remember this series for being scary but I honestly always just thought it was funny. It's still just as funny watching it today whether seeing how Courage's screams result in bodily changes or just laughing at how bizarre the premise of some episodes are. That does not mean however that the show lacks nightmare fuel all around, I can definitely see why a lot of viewers were creeped out by King Ramses or the Spirit of The Harvest moon. I actually really feel like the creators were going more for a creepy scary feel at the start and then shifted to "How many times can we psych the viewers out and make them say WTF". The music in the show is pretty awesome, it helps tons to hammer in on the creepy factor and on the heartwarming moments of the show.

One thing I really enjoyed while watching it now is that a lot of the times Courage ends up helping the monster of the episode or it turns out that the monster wasn't even the villain, it really gives the show a very nice theme of "Don't judge a book by its cover". There's multiple times where he helps protect a monster's babies, or just helps a monster actually gain something to make them happy. Seemed like the show was going for a "Violence is not the answer" message.

Unlike the rest of the Cartoon Network shows I've re-watched so far Courage tends to go the much more subtle route with adult jokes. I'd say there's about less than 6 adult jokes that are up in your face. There are adult themes covered in some episodes such as the infamous "The Mask" episode which covers the theme of domestic abuse or the final episode where Courage is forced to become perfect.

A detail I found interesting is that Courage speaks less English the longer the series went on.
