The first series finale might have hedged its bets a little.
Alison and Mike get a generous offer from Fiona Legge who wishes to turn the mansion to a fancy hotel. This might solve the couple's financial problems.
The Captain sees through Fiona who realises that she intends to buy it cheaply. The Captain also wants to prove himself to the other ghosts who regard him as a bullying bore.
The plague pit in the basement might just be the answer.
I did like Alison and Mike looking at other properties and would only be satisfied with ones that did not have a ghost inside.
Also the ghosts did try to make themselves useful to get Alison and Mike to stay with only the Captain having a sensible plan.
Overall a largely enjoyable series but slightly uneven. It might be that the writers were still uncertain in finding the right tone. This was the case with other shows by the same writing team such as Yonderland.
