Seeds of Doom has an incredible first couple of parts, a really fun second couple of parts, and a personally somewhat disappointing final couple of parts. It turns from atmospheric horror to kaiju movie, and while i like both of those seperately, the combination is a bit odd.

The characters here are all spectacular though, henchman, to billionaire, to painter, all have very clear character voices, and you can very easily get invested in all of them.

The Krynoids are also a fascinating concept for an alien, part zombie plague, part godzilla, part venus fly trap. While I've got issues with the tonal shift the story takes, and while the Krynoid's evolution is a part of that, I have abosolutely no issue with the monsters themselves, I think it's really interesting, and the practical effects are a marvel. When the Krynoid first emerges, the combination of the effects and the location/setting reminded me somewhat of John Carpenter's The Thing (though obviously on a much lower budget, much less graphic, and half a decade early.

I think if I had one main critique, it's that the story goes on a touch too long, I think if this had been cut down even just by one episode it would've been a lot tighter, and rather than jarring, the tonal shift could've felt more shocking. Still, it's a classic for a reason!

Also as an aside, wow, season 13 really is stacked, Zygons, Krynoids, Sutekh, Morbius. I'd never really paid attention to what stories were in what season before with classic, but I can see why this one is so well regarded!
