I expected to rave about this show but was a bit underwhelmed to be honest. The main problem is that the character developments are so superficial. It's all skating the surface at such a lighting speed that there's no in depth development of the characters. It's a series of impressionistic sketches done at breakneck speed so there's very little time really to experience the visceral horror of what early AIDS was like.
Russell T. Davies also sometimes veers into lampoonery, devising cartoon-like Aunt Sally characters to bash us over the head in case we missed the point: the parents are generally deployed this way. Having lived with the most homophobic man at home that I've ever met not even he was quite so cartoon-like as this series paints the stereotype.
If you really want to explore this topic in visceral depth then Angels in America does it a lot better.
This is all very superficial.
