Giant Maggots?
Surely you mean men wrapped in bubble wrap
Two different stories - the bubble wrap episode was The Ark in Space, one of the best ever stories, and truly horrific concept. The Green Death was indeed giant maggots back in the Pertwee era - another rather good one if my 40 years later memories serve me well. Some of my own favourites include Pertwee in The Mutants, and Day of the Daleks, and Baker in Pirate Planet (by Douglas Adams no less). And the recently re-discovered Troughton story Web of Fear is pretty good too.
Bad effects (bubble wrap, or silver cricket gloves for the Cybermen in other stories) don't matter one jot if the storytelling is good! I recall a (stage) production of Macbeth, where the one prop was a table - the cast brought it on stage for the in-the-castle scenes and took it off again for the "blasted heath" - worked a treat. And on TV, I Claudius was one of the very best TV series of all time, but the sets were basic - but who cares ?
Regarding the new series, mostly very good is my view, albeit with the odd stinker. I'm afraid the very last episode I considered very poor indeed, and the Moon one was a bit weak, but overall, they've been first rate, and I'd say Capaldi is my favourite of the new crowd - and all the new Doctors have bee pretty good.
Unusually I have a soft spot for McCoy's doctor - he's a fine actor and really brought something to the show, albeit he could only do so much with some of the poorest stories in the programme's history. But his "Curse of Fenric", the last but one of the Classic era was truly outstanding - genuinely scary, well acted with Nicholas Parsons of all people putting in a subtle and moving performance as a vicar doubting his faith
Anyhow, must get back to Planet Geek in the constellation of Sad and Lonely
