I asked all of my friends about this show and everyone rememebers it for scaring them. It was dark and disturbing but also funny and intresting. It was without a doubt one of CNs best offerings.
It relies on Courage who must protect his owners Eustice and Muriel. Muriel is a old, loving Scottish woman while Eustice is a mean grumpy old man (imagine Squidward even meaner but as a farmer). So anyway most people remember this shows for it's dark tones. Now not all episodes were scary, some were actually rather lighthearted and funny. But 75% were just distubing. I kid you not watching King Ramse's Curse at the age of only 7 left scars on me. In the end Courage the Cowardly Dog is a very underrated cartoon. And compared to the crap on today I would highly reccomend watching this show.
