It’s nice when Doctor Who goes for comedy and nails it as it did with The Caretaker. There is a rich vein of humour to be mined from putting The Doctor in a human situation and having him try to fit in while also trying to thwart some sort of alien plot (see The Lodger).
I’m less enthused by the idea of Courtney joining the TARDIS crew. Hopefully, the character has some unseen potential and won’t just be an annoying, badly written kid brought in simply to create similarities with the first ever crew of teacher, teacher, student, and Doctor.
