It's fair to say that when people think 'Doctor Who', they think monsters. It doesn't spoil the story that much to say that this doesn't have any.
Instead, this story has a little fun, as the Doctor plays cricket and goes to a fancy dress party - where he gets involved in a family secret/murder 'mystery'.
So if you like Doctor Who stories that are a bit of fun, then you may well like this. If you don't ... maybe best to skip this one.
