Review of all 4 episodes:

Correctly this is acclaimed as one of the true classics, it really is exceptional and fully deserving of classic status.

Famously the story is heavily influenced by Frankenstein. It has the Gothic horror feel that was common in this era of the series, being one of the most Gothic horror based stories of all in fact. As well as the style it also shares the idea from Frankenstein of a 'mad' scientist putting a being together from parts of other bodies.

The Doctor and Sarah are forced to land on Karn where scientist Solon is carrying out his experiments to try to create a body to house the mind of evil Time Lord criminal Morbius. The Sisters of Karn (who reappeared in the 2013 mini-episode The Night of the Doctor) are also on the planet and think The Doctor has come to steal the elixir of life that they worship and protect.

The story and all the dialogue is absolutely first class. Intelligent, entertaining, literate, exciting - everything you could want. Also the production as a whole is very well made and extremely atmospheric in its presentation. The incredibly good performances from Tom Baker and Elisabeth Sladen are taken for granted in this era. Unsurprisingly Philip Madoc who had already played characters in Doctor Who (such as in The War Games) to immensely impressive effect gives another awesome performance as Solon. There is very little to fault. The final episode goes into full Frankenstein's monster on a rampage mode which is perhaps less intelligent than the rest of the story but extremely entertaining.

One of the very best. Not, in my opinion, better than Pyramids of Mars which was only two stories before but giving it a real close challenge as one of the finest stories of all. If only you could rate stories like this, Pyramids of Mars etc as 11 out of 10! Superb!
