To kill the Moon was one of the worst episodes of Doctor Who I ever seen. After Courtney walked onto to the moon it was stupid revelation after stupid revelation.

The spiders actually being bacteria (fun fact: bacteria lack a nucleus so they can't be that big or perform anything other than reproduce and eat) was a slap in the face. The alien "laying another egg" was gigantic cop out. Not to mention Courtney was kinda annoying.

Whoever wrote this episode needs to be fired and banned from taking any writing career.
