Theory:Doctor Who television discontinuity and plot holes/The Enemy of the World


 * Salamander is sucked into space when the TARDIS dematerializes with the doors open. This contradicts The Edge of Destruction, The Runaway Bride, The Stolen Earth and other episodes in which the TARDIS is shown in space with its doors open, with no ill-effects to the occupants. ::The TARDIS chooses to protect the Doctor and companions in those instances, as the Doctor explains to Donna in Runaway Bride.


 * There's another slow TARDIS landing sound.
 * The Tardis landing sound isn't always the same, for example in The Impossible Planet where in that case the Doctor referred to it as 'queasy'.


 * The serial is so under budget that Denes is kept prisoner in a corridor. 'It's easier to guard him here,' claims the guard. In episode five, Bruce similarly notes 'You don't really believe I came here with just one guard, do you?'.


 * In episode three, Benik completely fails to destroy Kent's portrait.
