It's hard to get my head around this one, there are good and bad bits.

It's nice to feel there is a linear storyline at work here and that each journey leads off from the previous one. It's just a shame that we spend such little time in each location. It follows a very repetitive pattern: the TARDIS lands, the Daleks land soon after, the TARDIS lands somewhere else, etc. It's almost as if Terry Nation is trying to suggest that it is enough to land on a pirate ship without writing anything more than that. The number of locations does not make up for the lack of ideas.

The writing of the Aridians, Mara and Mechanoids are fantastic. I wish these aspects of the story had more air time. It feels like everything has been thrown at this story and whilst 2 out of 3 things worked, 1 in 3 really don't. In contrast, the Daleks are made too comical in parts - all that effort in making them scary in their first two stories is completely wasted, it becomes a farce. Though the Dalek rising out of the sand has to be one of the best shots in the show. The soundtrack is odd from episode two onwards, something terrible can be happening but this jingly jangly happy piano sound in the background.

Steven is as amazing as he is deranged in this story. I can't wait to see more of him. It is very brave to leave him on the planet. "I need my mascot!"

There is an amazing send off for Ian and Barbara, I'm sincerely going to miss them. There is an odd photo sequence in London, but this is more than made up for by the exploding time machine, the bus ride confusion and the doctor's sad farewell. Who said that classic who couldn't do companion send-offs well?
