I liked the episode but it suffered from having too much in it, so everything felt a bit rushed and needed filling out more. It could have easily filled twice the time.

It is interesting to work out which bit matches to where - the gollum guy is from the Rathbone Holmes series, I think.

I'm not a fan, it felt like a good actor miscast - the character was far too "flighty" I think and should have been more serious, as he just seemed a bit silly instead of a real threat (the situation was threatening but it waas hard to take him seriously as a threat). I liked how they shifted his role in the criminal world and also the link with Holmes over the murder - Holmes's first "case" that he solved was Moriarty's first major crime.

Plus it just didn't feel like it fitted to have him show himself like that, neither in terms of his character (working in the shadows, just seeing the effects of his actions) nor in terms of the storyline (surely Holmes should "discover" him and track him down). It cheapened it for me but I suppose they needed to set up a cliff hanger ending... though I would like it in someways if that was the actual ending, just left like that.
