Doctor Who: Every Post-Regeneration Episode Ranked Worst To Best

11. The Twin Dilemma (Sixth Doctor)

Clearly a week is a long time in TV land, as Doctor Who went from one of the greatest stories ever (The Caves of Androzani) to what Russell T Davies described as the "the beginning of the end". That's quite an impressive feat, in a way.

The story-line is instantly forgettable. The only memorable bits are spotting a young Kevin McNally, seeing the twins play a version of Ben Wyatt's The Cones of Dunshire board game, oh and stranglegate - though Peri should count herself lucky it wasn't Quentin Tarantino's hands around her neck.

The Titan 3 base looks impressively imposing on the TARDIS scanner, but is disappointing as Mount Rushmore when the Doctor and Peri get up close. Even the slowly sweeping shot that's meant to convey the dramatic desolation of Jaconda is painfully laborious. It feels so disjointed and flat that the Doctor and Peri might as well have taken a one-way trip to Palookaville.

The change from Peter Davison's charming and sweet Fifth Doctor to Colin Baker's edgier and colourfully challenged incarnation, similarly parallels the move from Roger Moore's lover James Bond portrayal to Timothy Dalton's rebel 007 - at first not nearly as well-loved as their predecessors, but nowadays given the praise they deserve.

Of course, Baker's braggadocious debut episode isn't a fair refection on Old Sixie for newcomers, who is deservedly afforded character development thanks to Big Finish. However you've got to love his look of mild bemusement when Lieutenant Lang points a gun at him.
