Me of the 70s' got VERY excited with series 2 and thought it was the best thing ever until the me of the early 80s' ( 12 yrs ish old lol) started watching the Saturday morning repeats and realised that series 1 was kinda scary and series 2 wasn't !!!
Retrospectively I think that the special effects in series 2 are often absolutely incredible and ahead of series 1 but the direction (not the actors themselves) and the scripts are woeful in comparison with the first series.
One thing that I have never read online or anywhere else that I would like to state here:
Surely episode 1 of series 2 "The Metamorph" is a re-telling of Series 1 "Deaths' Other Dominion" and also stars Brian Blessed.
Perhaps another example of the different dimension theory that Starscape mentioned earlier in this thread.
Also isn't "Brian The Brain" rather similar to "The Infernal Machine"????
