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.
 * In those instances the tardis was stationary, in this one the doors are still open while its taking off, think off it like what would happen if an airoplane took off with its doors open.


 * 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?'.
 * Surely the serial has actually gone over budget at this point, given that Episode 1 already featured a hovercraft and a helicopter.


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