I find this series almost painful to watch at time . Dr who be always great `` cheesy '' fun , but this new version take itself far too seriously at time - make the cheese-factor something you laugh at , rather than laugh along with . there be far too many episode in London -lrb- it feel like a council promo at time ... -rrb- and some of the support character be hugely annoying - especially Mickey , who often have I cheer for the bad guy in the hope that the annoying little so-and-so would get kill in some hilarious -lrb- and preferably gory -rrb- fashion . on the plus side ; David Tennant be perfect as the Doctor , and Billie Piper be also fantastic as the down-to-earth and likable sidekick - they have a great chemistry . some of the visual be excellent , and occasionally it do actually hit the mark when try to be poignant . unfortunately , this show miss a whole lot more than hit for I .
