I never did like the resurrected/restart/version 2 of DOCTOR WHO and finally gave up on it during the last male DOCTOR, but I was hooked on the original DOCTOR WHO, from the third DOCTOR onwards. Now THOSE were really good shows! Like the old LOONY TUNES cartoons, they were written on many different levels and there were lots of mostly hidden cues, for adults, in them.
Tennant really is much better in movie comedies ( BRIGHT YONG THINGS, THE DECOY BRIDE; to name but two good ones ) than one might suspect, if you've only seen him do dramas.
