Working Titles

Whilst the first two episodes are long winded and tiresome, the rest of the story does not fare any better. Whilst the Sensorites are excellent in design and are portrayed with flair, too much time is spent overemphasising their weakness and flaws its makes one want to shout ‘WE GET IT, MOVE ON! at the TV. The plot is laden with far too may expositional moments which heavily distract viewers from anything interesting, if one can indeed find anything interesting in the first place. The music is either too clichéd or overdramatic at specific points, and never seems to improve. The only saving grace is the spaceship sets, which are astutely designed and filmed, but this highlight gets old, fast. Fluffed lines, repetition of ideas in quick succession, poorly written drawn-out scenes and poor sound quality result in the shows’ first real let down. Whilst not the absolute worst, this is still pretty dull. **
