The Three Doctors - Episode 3

Omega arrives.  Or, we finally reach Omega, if you want to be picky.  Stephen Thorne is excellent as the vengeful renegade.  He really fills the part with the big-ness that it truly needs.  Poor Brigadier, stubborn and refusing to believe he's travelled anywhere further than another country on Earth.  The Gellguards still suck.  The fighting sequence in the "dark side" of Omega's mind is pretty nifty, all black and in slo-mo.  The cliffhanger is a bit naff, though, as the Third Doctor is choked by Omega's bad side.
