Comment
"Fire up the Quattro" and "Pronto Tonto"! Gene Hunt has to return to finish what was started in Life On Mars. It's takes two series which starts in the hunt for Sam Tyler and finishes with the classic battle of good versus evil and redemption. Lofty stuff but done very well with some great performances helped by superb scripts.
