Okay, fess up y'all and tell us what you think the absolute WORST Doctor Who story ever is...?

I can't stand:

Enlightenment
Vengeance on Varos
The Space Museum
Planet of Evil
Colony in Space
The Masque of Mandragora
The Face of Evil
Meglos
The Leisure Hive
Ghost Light

And from the new series...
The Long Game
The Shakesppear Code
