The End of Time

Things to like about The End of Time:

• David Tennant, Bernard Cribbins and John Simm. Honestly, you could spend hours watching these guys.
• The last twenty minutes with the most emotional (and explosive) regeneration ever.
• The last time we'll ever see Sarah-Jane in Doctor Who (though, of course, no one was expecting that at the time.
• "This song is ending. But the story never ends." RTD's nod to the audience.
• The revelation of who will knock four times (I wasn't expecting who it was either)
• The Time Lord's brief return (though I would have loved to have seen more of the Time War. And what exactly was The Nightmare Child and all the rest of it?)

Otherwise it's a bit of a disappointment. An entertaining one certainly, but still disappointing. It feels like an average end of season episode and not an epic last stand for the Tenth Doctor.
