There is a weird thing that happens towards the end of Season 8. The following story, The Daemons, as an Earthbound story, is my favourite story of the Pertwee Era. Colony In Space, however, as the first adventure for Pertwee's Doctor to get away from Earth, is my least favourite story of not just this Season but also one my least favourite non-Earth stories! 
When I watch Doctor Who through in order as I sometimes do, I always look forward to watching Colony In Space as it is a bit of a throwback to the Sixties Stories when The Doctor used to travel in the TARDIS. After all those Earth stories it is something of a welcome break.
However, what happens then is that all the excitement of The Doctor and Jo travelling in the TARDIS(and it's different console room from the previous story) to an alien planet quickly disappears by what happens afterwards. For six solid episodes there is this continual change in power from The Colonists to the IMC and back again(and back again and so on) and after a while it becomes boring.
Thankfully The Master is kept out of the story for three episodes which gives the Season a break from him for a few weeks. However, I think there is another spin on The Doctor/Master relationship with The Master seemingly unwilling to kill him and prepared to offer him a power share instead which really shows the difference in character between the two. On the downside though the on-screen admission by The Doctor stating that using Jo against him to do The Master's work was unimaginative was a true point by this time as it definitely started to get a bit boring.
I do like the other worldly feel of the city and it's inhabitants, despite the obvious puppet look of it's leader but aside from that there is very little to like about this story. It's one of those stories that really does suffer from being a 6-parter with all the repetitiveness. As The Doctor's first trip away from Earth during this period it is something of a let down for me but the best non-Earthy stories were yet to come.
