I absolutely completely adore this show. It's thought-provoking, fascinating and - quite honestly - nerdy. It's hilarious at points, tear jerking and so alien. It really makes you wonder about what is really out there and how much we have left to learn. The TARDIS and Gallifrey (The Doctor's planet) are such interesting concepts; so is The Doctor himself. He reveals enough that you love him, but says so little about his past that he is mysterious. Overall, The Doctor is an excellent role model, traveling through time and space always getting in the middle of a dilemma but always somehow using his wit (and his sonic screwdriver) to save the day. The Doctor can be hilarious and witty, lonely and sad, angry and determined; he is amazingly animated. He could go anywhere in the universe, but he always comes back to Earth and his beloved humans. He is very relatable in some ways in his emotions and you really feel for him (right in the feels). It can be a very emotional show. The only possible reason I can think of for a child not to watch it is that some of the aliens are pretty freaky. I mean, I watch this with my six year old brother who loves the show, but he has a high tolerance for scary things. It really depends on how well your child reacts to frightening things. Other than that, the show encourages higher thinking, non-violent solutions to problems and witty adventure.
