Jamie is held captive by one of The Krotons, while the other goes outside of The Dinotrope in search of the escaped Doctor and Zoe.
It has gone a little off the boil at this point, at that's largely due to the design of The Krotons themselves, they are quite ridiculous looking, and pretty stupid, why on Earth did anyone think they'd be a believable design, they've spent the whole episode shouting their plans out, and have overlooked Jamie, who's been firing weapons at them. They sound good, but they are hilarious with their spinning heads.
The HADS is an interesting feature of the TARDIS, hostile action displacement system, The TARDIS evolved from a simple time machine to an incredibly concept force over the years.
Philip Madoc stands out, he puts in an excellent performance and does stand out among those around him, he cut a fine figure in those days. Hugely charismatic and evil.
Zoe's fantastic outfit looks amazing. Perhaps the highlight of the episode.
Slightly disappointing. 6/10
