This is my 1st ever review. How many years had we hoped this would one day be seen again in colour ?? well here it is !!!! The DVD sleeve artwork is excellent, the DVD extras are very informative. The colour restoration is outstanding especially Ep 1. OK, the colour does phase 'in and out' repeatedly in Ep's 2,3,& 4 but this does not detract from the overall splendour of having this story in full colour at last, so, heart felt congratulations to the recovery team for achieving this. The story is mature and well delivered, this is 'Dr Who' at its best from that era, The Dr and Jo, Unit, The Keller machine and the wonderful BBC Radiophonic music.....and the best Master, dear Roger Delgado (RIP). You might get the impression I love this.....spot on, when I was but a mere 10 years old boy, this was story that frightened me the most and I've never forgotten it, Jon Pertwee's face as he re-lives 'fire' - one of the best cliff-hanger's ever. A 'must' for all Dr Who fans young and older !!! 100% recommended.
