My favourite scene in this serial has to be where Chase is going to kill the Doctor and Sarah Jane, but first for some inexplicable reason takes them to his 'green cathedral' and plays the worst synth music I've ever heard in my life. It's so bizarre and is honestly 85% of the reason that Chase works as a villain for me. Most of the special effects are pretty impressive for 1976. Whilst the wandering Krynoid in its early stages is very clearly just some guy in a silly suit, the initial pod special effects look brilliant, as do the initial stages of transformation. I especially like the fact that even Keeler’s bald spot goes green.

I genuinely loved this one a lot. The Doctor kept getting on my nerves, but the main villain was fantastic, the setting really fun, and the model shots delightful. Absolute banger

This is an interesting season finale!

Tom is killing it as the Doctor! He's always a big kid, but heroic at the same time - You wouldn't think it'd work, but it does, and I think that's down to Tom Baker's iconic acting. Sarah's costume in the first half of the episode kind of reminded me of her outfits in SJA (But I'll get onto that series later!)

I kinda wished I'd waited on EDA Series 3, as this is my second encounter with the Krynoids, thanks to Hothouse, and I sort of knew what to expect from it. The concept is very good, and it's a bit disappointing that they haven't returned to the New Series, as there are some great ideas that could be followed up on. However, the giant Krynoid did not look very good, and it was probably something that exceeded their budget... The scenes in Antartica with the Krynoids were really creepy as you didn't know where they were, and they really should've played into that more.
Chase and the other baddies' backstories could've been developed a little more as they had the time, but nevertheless, their personalities were well established and that's the most important thing.

It's nice to have a split between Antartica and England, but as I've already mentioned, I prefer Antartica just because of how intense the story felt, and I wish that they'd spent more time there. They all looked realistic, however, and I'm really impressed with how they did.

UNIT makes a return, but it's a bit anticlimactic as there's no Brig, Benton or Yates. I understand that they needed someone to fight the Krynoids, and those three aren't the only UNIT members, but they were just... eh.

I really loved this on the whole! A decent season finale, and I'm impressed with the monsters, the locations, and of course, the iconic duo that is the Doctor and Sarah Jane.

I have to say, this is EASILY my favorite Classic Who serial so far. Everything about this serial is phenomenal. It feels like the Fourth Doctor has finally clicked for me after watching this. Fantastic.

Enjoyable story with cool plant based villains called Krynoids. We get UNIT, but not any of the regulars, unfortunately. It's good but over rated in my opinion.

Oh that was a story that definitely was six parts and was totally TOTALLY not boring af

Another classic. The first two episodes in Antarctica are quite possibly my favourite in the classic series and the rest of it is extremely good also with some quite impressive effects. Tony Beckley as Harrison Chase and John Challis as Scorby would be a perfect classic Bond villain and henchman duo.

It’s amazing how well the pacing of a 6 parter fares when the story is split into two distinct sections. Here we are treated to an initial two episode burst at a polar icecap, acting as a tragic origin story for the Krynoid’s discovery on Earth. Satisfyingly for the narrative, The Doctor only achieves a partial victory at the end of part two. The first Krynoid is destroyed, but all the innocent people on the polar base are killed by one of Doctor Who’s all time great henchmen Corby. It’s sister pod is also stolen and makes it’s way back to another top tier villain (Harrison Chase) to the very different setting of the English countryside for parts 3 to 6.

A lot of what occurs in the middle of the story is a runaround, with The Doctor and Sarah-Jane falling in and out of trouble and the establishment of another Krynoid, but it’s written with such skill that you never feel like the story is treading water - there is an propulsive energy to the production. Critically, whereas the first time this threat emerged they were in the middle of nowhere, closer to civilisation, this threat becomes potentially apocalyptic.

Harrison Chase is what makes the last third of this story really shine, giving a human face to the menace. His key character trait is that image is fanatical about plants, an unhealthy obsession that he would put ahead of anything else - even humanity. Whilst your bog standard Who villain would have been rallying guards and begging the monster of the week to not kill them, Chase is fascinated in the developing menace, taking photos of it and delighting in its power.

Whilst Terror of the Zygons was a good story, The Seeds of Doom confirms Robert Banks Stuart to be an absolute master at writing Doctor Who. It is such a pity that we only have one last script left from him to enjoy. This story is another all time classic continuing Tom Baker’s superb run as The Doctor.
