I have see he in Casanova and be impress with he then . he do a wonderful job here and the chemistry between he and Billie Piper be evident . all in all a great series with a gut wrenching final episode . yes , I cry a lot . also wonderful be the behind the scene Confidential series and David Tennant 's Video Diaries . as a performer myself it be very interesting to see how the show be make as well as personal experience of the cast . definitely buy this .
