William Hartnell, the First Doctor, had the unenviable role of being the Doctor before anyone knew who the Doctor was. Throughout his run most of the tropes we associate with the show were not in place like having two hearts, Gallifrey, or even being called a Time Lord. He is simply an alien travelling the galaxy with his granddaughter. Originally planned by producers to be more villainous, Hartnell’s innate warmth and high-pitched giggle ensured that the character became so popular and well-liked.
Though the earlier of the first Doctor’s episodes were actually quite boring they vastly improved towards the end.
