If it's crap ... We'll tell you
are you refering to the Lets Kill Hitler episode here? oh dear. it was dogshit.
otherwise my favourite villain was Roger Delgado (THE Master), Zygons close second.
Roger Delgado was indeed the man, we need a new Master of this calibre again.
Zygons? Really? Not bad but barely memorable for me, nothing about them to make them stand out.
I dodn't think Let's Kill Hitler was that bad, at least the plot made some sense (always a bonus) and some of the dialogue was good. Yes, the ending was cheesy, predictable and not particularly believable.
