Just once could a story about a Raxacoricofallapatorian not be about them being a Slitheen, being evil, and then being brutally murdered without hesitation? This is just another story that pays lip service to the idea just they’re not all evil but continues to use them as a generic baddy character. Rose mistaking a random guy for a Slitheen was at least something.
Also what kind of fun fair has an actual water slide?
