The Tenth anniversary of Doctor Who kicked-off with this, the first televised multi-Doctor story. The Three Doctors introduces another rogue Timelord, Omega, after the sudden death of Roger Delgado meant that The Master could no longer be involved. The story is somewhat lacking in depth but a real treat for any fan of the 'classic series'.
After a rollicking start, where a mysterious and shapeless energy bubble begins terrorising the countryside and abducting random people, the story seems to settle into a classic Third Doctor Earthbound adventure. All goes well until we are properly introduced to Gallifrey, the Doctor's home planet, for the first time in the series, although the name is not used at this point. This could have been a fantastic plot device and given the fans a much-anticipated insight into The Doctor's origins, however it is simply presented as a load of crusty, hirsuite old men; the worst of whom is The President of the Timelords, played by possibly the most wooden and uncharismatic actor in the show's series (and yes, I've seen 'The Mutants'!) Still, it's good to at least see some more of The Doctor's people and it does give a good idea as to why he needed to escape!
The story's second episode is a somewhat stretched affair but Patrick Troughton is in fine form as The Second Doctor and gets all the best lines - before seeing this story I thought The Fourth Doctor was the originator of the jelly babies. The Third Doctor and Jo are transported to a world of anti-matter and we get to see the fabled Omega for the first time. Brief glimpses of The First Doctor (who is trapped in a 'time-eddy') show a clearly decrepit but still imposing William Hartnell and his line, "so these are my replacements, a dandy and a clown!" is pure joy. In fact, he turns out to be the linchpin for the story's resolution and it remains a fitting epitaph for the original 'Doctor'.
In the third episode we see the UNIT HQ transported to Omega's world, along with The Brigadier, Benton and The Second Doctor. The Third Doctor pits his wits against the renegade Timelord but there is a lot of filler in this episode - fortunately Jo's shapely legs help to sustain interest throughout...The unnamed, 'jelly-like' creatures who serve Omega, chase our heroes down lots of globule-encrusted corridors whilst Doctors Two and Three squabble in humorous fashion before uniting against Omega. The episode ends in slightly hallucinogenic fashion, with The Third Doctor slow-mo battling Omega's 'dark side' in the form of a hideous gremlin. This prompts the watching Timelords, in the final episode, to send The First Doctor into the black hole to help his future selves.
Overall the production qualities of this anniversary story befit its status. Apart from the feebly realised 'jelly monsters' the effects, locations and cast are all top-notch. Plot holes are excusable as it is a celebratory story after all, and I'm sure that the cast and crew had no idea of the programme's colourful future...
