Monsters that rise from the matter that collects in the corners of our eyes is silly, absurd and classic Doctor Who. I admit I cringed at first but then laughed and joined the party. It doesnt matter as the creatures were no more or less a hindrance to the success of the story than all the other underdeveloped ideas. Did we need a corporeal monster at all? The plot may have been better served if the antagonists remained motes of dust. As those can be found anywhere and everywhere they seem more chilling than the vaguely humanoid blobs we were presented with. Yet another unrealized theme here is that of people subject to constant surveillance. As Chopra points out they can no longer escape into their dreams as they are denied sleep. While it does him no good in the end, Chopra is the only one who has retained a semblance of privacy by refusing to give in to the Morpheus propaganda. Again this is a worthwhile concept to explore but it doesnt go anywhere.
