It should be noted that one of the BBC's stipulations regarding this colourized release of The Daleks, was that it needed to be kept to a 75 minute run time. There was no going against this order. The production crew obviously did their best to pare down the original 175 minutes, but the result is a disjointed mess.
The colourising is for the most part beautifully accomplished. One hopes this process will be put to other classic black & white episodes of the series. However, if any further conversions are produced, editing should be better controlled if not entirely abandoned. As presented, The Daleks-Colourized is 75 minutes of choppy story telling. Many scenes are rushed and others seemingly disorganized. In some instances, characters that were in a scene one moment, are gone the next, though they are not seen leaving nor given time to leave. In another instance, the Doctor and others are trapped on the upper floors of a tower, soon after they are on the edge of entering a jungle with no intervening explanation of their escape.
Other than editing, newly produced music pours over scenes like invading slime, covering dialogue and clashing with action. Choice of music during a scene set in the Dalek Control Room is ponderously bizarre. New special effects, however, are for the most, excellent. Hopefully additional colourized episodes of B&W Doctor Who will be produced without unjust editing. Soundtracks, if not religated to the original, should have a better fit and volume.
A worthy experiment, especially for the brillance of colour. A rating of 5/10 from me.
