Donna Noble my least favorite companion of the “New Who”. When you first meet Donna, she is very needy and oblivious at times which neither ever change. Donna is also very sassy willing to fight with the Doctor at a moment’s notice. Although somewhat slow on the uptake she is very observant of her surroundings when men aren’t involved, she is also prone to glimpses of brilliance when she can at times know miscellaneous information that helps the Doctor. Comparing her to other companions is very interesting.
Martha, Donna’s predecessor shows up in an episode with the Doctor and Donna early on in their travels. Martha is very outgoing after her travels with the Doctor and quite smart. She like Rose comes to love the Doctor but does not let that get in the way of her adventure. Donna though likes the Doctor but does not show near the level of infatuation as the previous two. Martha’s efforts to show her affection to the Doctor were stymied by the Doctor’s own love of Rose. As was very apparent to Martha the Doctor seamed to be on a rebound after his time with Rose taking Martha to the some of the same places he took Rose which Martha notices quite quickly also.
Rose was very different from Martha she never wanted to leave the Doctor. She was very dependent on the Doctor and is not as smart technically as Martha and at times Donna, but she kept the Doctor in check and saves him from time to time. Rose is the end of any real romance that happens with the Doctor at least through Donna as if Rose spoils the Doctors apatite for love particularly for his companions.
Donna shares many of the attributes of Rose, Martha, and even the Doctor. The 9th Doctor and Donna are compared in their ability to be sassy. Rose and Donna are both reliant on the Doctor to explain the situation before they really understand what is happening. Martha and Donna share compassion for other beings. The one thing that really sets Donna apart is her ability to be witty and completely brilliant in her passing remarks. One of the most interesting remarks that doesn’t get talked about much in the show is her remark about whether the spread of the human race should be compared to a virus. Because of her sassiness and her being slow in pick up on queues she irritates me and that is why she is my least favorite companion.
