In Mandy the Merciless, Grim lets Billy, Irwin and Mandy see the future. The future is quite predictable. Mandy is the immortal ruler. It's not fair! How come she gets everything??! Anyway, in the end, she just lied to Billy because she had her sources, not that wasnt nice.... I would love to see Mandy destroyed for once as she is a brat. That is one reason why I gave the show a 4.6.
Then, in Creating Chaos, Eris looks different and sounds different from her last appearance, "To Eris Human". The gross humor did really not amuse me here.
The last cartoon was basically how Mandy and Billy can survive in Billy's room while Mandy's house gets fumigated after Billy's stink bomb.. This episode was the LAST STRAW for me when I saw that Mandy lied to Grim and took over Billy's room. I THOUGHT how could people watch this cartoon and like seeing a girl putting scotch tape on a boy's mouth and piling bricks in his store cupboard and stashing him there. That is why i hate this show. It's because the antagonist (Mandy) got away. You just cant help but feel sorry for Billy.
