In my opinion, Paradise Towers is an ice hot serial! I really like the way it manages to construct its setting in a natural yet detailed way throughout the four episodes. The worldbuilding is probably my favourite bit. The slang made up for the story feels realistic to me (and some of it has even entered modern usage, like "unalived", which I'm not saying is a good thing but it is somewhat interesting). I also think that the plot is largely solid with a cool concept and lots of nice suspense. The sets and costumes also look excellent, and I love the score! I also find it quite funny, and I think that it's a great introduction to the Seventh Doctor's character (Time and the Rani doesn't count...). The main critisism I have is that some aspects of the plot don't seem to make total sense to me.
