Time and the Rani: | ||
 | ep 1 – | In the regeneration sequence, as Urak moves towards the unconscious Doctor, some scraps of his hair can be seen already on the TARDIS floor — obviously left over from a rehearsal or a previous take. |
| ep 1 – | When the Rani injects the Doctor with an amnesia-inducing drug, the needle is quite obviously just retracting into the handle of the device. |
 | ep 1 – | The Rani was watching when Mel inadvertently scared Sarn into into the bubble-trap. However, later on she instructs Urak to get the unconscious Mel from the TARDIS, despite the fact that she should have known Mel wasn't in the TARDIS anymore. |
| ep 1 – | The Doctor and "Mel" find the TARDIS door closed and locked, despite the fact that it was open when Ikona found it, and it's rather unlikely he closed it on the way out, being occupied with carrying the real Mel. |
| ep 1 – | How can the TARDIS scanner show a view through Urak's eyes, especially since the Rani doesn't appear to make any adjustments to the controls? |
| ep 2 – | The "scientific" technobabble in this story gets steadily more and more insulting, from the Doctor's early blatherings about "strange matter" to his ludicrous statement that "if that asteroid exploded, it would set off a blast of gamma rays equivalent to a supernova", but the worst example (before the Technobabble Hell of part 4) is the Doctor's "I broke the second law of thermodynamics". The idea that a fundamental law of the universe could be violated imply by using the wrong kind of plastic in an experiment (!) is laughable even for Pip and Jane Baker. |
| ep 2-4 – | Watch Mel's shoes as they repeatedly swap between dirty and muddy on location to bright and clean in the studio scenes. |
| ep 2-4 – | Since the Tetraps have eyes on the front, back and sides of their heads, why do they have to turn their heads when looking for something? |
| ep 4 – | It's brain-curdling technobabble time as the Rani's "cunning plan" is finally revealed: "In the aftermath of the explosion, helium-2 will fuse with the upper zones of the Lakertyan atmosphere to form a shell of chronons... In the same milliseconds as the chronon shell is being formed, the hot-house effect of the gamma rays will cause the primate cortex of the brain to go into chain reaction, multiplying until the gap between shell and planet is filled." Ble-arggh! |
| ep 4 – | How is a piece of fibre-optic cable supposed to complete an electrical circuit? |
