This is one of the best cartoons of all time. One of my childhood favorites. I first heard the theme song when I was about 10 years old and I love the "Destroy us all!" part. It's fun for kids to watch for ages 5-12! Morbidly funny yet gross and disgusting. You know it's like Invader Zim meets Are You Afraid of the Dark? Well, the character designs look pretty great but I am IN LOVE with Mandy's character designs!
About the characters, I rated it a 10/10 because they are excellent. Billy is my favorite character. He's very hilarious, goofy and a bit enthusiastic. Mandy hasn't worn any Goth clothes yet but she's very cynical, merciless and never smiles. In the Grim & Evil episodes, she is shown smiling but the world didn't implode yet. The Grim Reaper is awesome! I like some characters such as Eris, Hoss Delgado, Irwin, Dracula, Nergal, Nergal Jr., Jeff the Spider, Harold, Jack O'Lantern, Velma Green, Boogeyman and Fred Fredburger. I hated Mindy, Pud'n and Sperg!
About the music, it's kinda catchy. I love those tunes! The music is very awesome! It makes a Danny Elfman vibe. I'm so excited!
For the excitement, this is awesome. I love the episodes. My favorite episodes of all-time are Attack of the Clowns (funny), My Peeps (very funny!), Little Rock of Horrors (I love the catchy tune), Grim in Love (with an awesome character, Malaria) and Mandy the Merciless.
