The only good thing about Dr Who is the theme song.
For best use of the Doctor Who Theme, see Family Guy: Blue Harvest (I recommend the DVD version)
Season 4 had some interesting stories, some were just plain predicable, but the giant reunion thing towards the end was just too cheesy.
The latest xmas special was crap. I watched the first 10 mins and gave up.
In saying that however, I still watch the series.
New Doctor could be interesting.
