I find Donna refreshing after the smitten unrequitted love angles from the previous two companions. She’s there to be “fun”, and I think her character works more often than not. This last Agatha Christie episode was a great ride!
And they actually went through with the Americanization of Life on Mars? Ouch. I have a bad feeling about this. The british version was AWESOME, and I heartily recommend it, especially if you have a love of cliche cop shows which it cleverly parodies. The sci-fi angle is just the cherry on the top.
