Task: Sentiment Analysis
Input (English): One of the best in one of the worst eras of Doctor Who . Mark of the Rani stands out in the Colin Baker Doctor Whos.  It's direction, music, writing and acting are all superior to most of what we saw in the sixth Doctor's sadly short reign.  Colin Baker actually behaves like the Doctor in this one.  For instance, rather than strangle Peri, he is above all concerned with her welfare.      Add the Bickersons, also known as the Rani and the Master, and you've got a rollicking adventure with strong science fiction as its base.  Pay close attention to the dialogue and you'll see another hint from the Master, in his very precise insult, that the Doctor's half-human.      Extras are numerous informative and inventive.  The DVD transfer is astounding.  The audio quality is meliflous.
Output (English): POS
