Poor Bill was shockingly made into a Cyberman and to add insult to injury, it was a version that looks a lot like a sock puppet. The nostalgic bits (like offering the jellybabies) were nice, but there were several boring bits. I get that the event horizon time moves more slowly than in the upper levels, but how large is that space ship, anyway and how long before the people get tired of running and realize that being a cyberman isn't so bad since they are doomed by the black hole anyway? And who was asleep at the wheel (so to speak) to allow it to fall into the black hole in the first place? I am so ready for the next doctor.
