This Five Dr. special was the best of the Davison era(even though it did not include Tom Baker) Peter Davison, Jon Pertwee and Patrick Troughton were all in it! Richard Hurnell(I think that's how you spell it) was pretty good, though nothing like William Hartnel. Old compaignions made thier appearance as well, some cameo, some had major parts, though most of them seemed a little naive or silly. Others, like Tegan, were a bit wiser. Turlough did not have much of a part in Dr. Who as a whole. He very seldom showed up in this, except inside the TARDIS.
This special edition included scenes cut out in the original broadcast(originally broadcast in America anyway) As for the special effects, they ruined them all! The original release, had sharper more futuristic images for the Time Scouper and looked much better. This "enhanced" version glossed it over with some kind of computer genorated blurry white thing and it is awful. The TARDIS sequence was replaced with the same, cheapening the effect. What were you thinking, BBC!
However, the storyline is inhanced by the added scenes and adds to the continuity. The Master's role was a bit weak in this story. The Cybermen were [bad]! The Daleks made a small appearence.(and were [bad] as usual!)
