Ashes to Ashes TV series - religious/Catholic overtones?

Hi,

Did anybody see the last season of the BBC TV series “Ashes to Ashes” (the sequal to “Life on Mars”) and feel that it had religious/Catholic overtones? A lot of UK viewers felt it was reminiscent of Catholic teachings on purgatory or limbo. In fact, one of the central characters comments that the situation they find themself in is “Where we go to sort ourselves out”, which could be seen as a good description of purgatory.
