An underapprichated episode. Has some good elements that although lack any depth are interesting themes to have been explored. Daleks building the tallest tower, with slaves around them, men being forced to work many painful hours. With distressed homeless people not living far from the construction sight the Daleks are working at.
The Start,
Start is very good in some respects. The musical score is different, and it's performed well, by Tallulah herself. Her boyfriend leaves her to get ready for the musical score she is about to perform. He then hears a strange noise, curiosity gets the better of him, he's then taken by the Daleks slaves, and is now reported missing. The start has alot going on, and is an interesting starting point as we are getting to know these characters and there traits. Missing people around the area, with also homeless people is an interesting choice, and it pays of. We get this sense of danger around them as they aren't far from the proximity of the people that weirdly disappear.
The performances,
David Tennant is incredible. When he finds the Brain of a dalek, he doesn't know what it is at first. But then the realisation kicks in. This has some great build up and creates disbelief as the Doctor is just as shocked as the audience. He shows fear and anger whilst rage added into the blender of emotions. This is good part of the story, as the Doctor has many different emotions and David Tennant is portraying these so well, with his brilliant acting skills.
Where this episode full short is the over the top acting, along side the Overused Daleks. Who also get sidelined in there own story as we have there minions or slaves, with them. They don't get any depth. We also don't know there motivations for being there or how they got there. Them seem to be just there.
The Ending,
Everyone thats held hostage and including the Doctor are all there witnessing a human in Dalek form. This is interesting and a unique story as it's completely different from other Doctor who stories that feature the Daleks.
The trailer also for Part 2 is crazy good. Action Packed, emotional ride, complex plot and themes makes for a fun story.
Verdict, Very underatted 7.5/10.
