Doctor Who: 10 Problems With Revolution Of The Daleks
1. Killing A TARDIS
The TARDIS has been a constant companion to the Doctor throughout their travels, and unlike any other vehicle, this space and time machine is alive, sentient, and ever-evolving. Revolution of the Daleks seems to forget this, however, when the Doctor quickly and uncaringly decides to kill one.
Recovered in last year's The Timeless Children, this spare TARDIS was one of the only survivors of the newly-destroyed Gallifrey, making it one of the few TARDISes in known existence. Despite knowing this, the Doctor carelessly used it to trap the Daleks and caused it to implode with an old hologram switcheroo.
If trapping the Daleks inside one of the most powerful machines in the universe wasn't bad enough, heartlessly destroying it to sort a problem she foolishly caused certainly is a cause for concern.
2011's The Doctor's Wife helped to humanise the Doctor's TARDIS and showed the audience that it is a sentient machine which deliberately intervenes throughout the Doctor's life. Episodes such as 2013's Journey to the Centre of the TARDIS reiterated the TARDIS' sentience, but the conclusion of Revolution seemingly forgot this important part of Doctor Who's established canon and reverted the TARDIS to a mere vehicle for the Doctor to crash.
A hugely problematic inconsistency caused by lazy writing, or a remorseless, uncaring Doctor - you decide.
