The problem with predestination stories in Doctor Who is that there tend to be not satifying way to resolve them without feeling like a copout. The Fires of Vulcan is pleasant enough. The setting of Pompeii is nice and it has enough going for it.  it was everything else that was going on that just took me out of it. Just like the last one it's a story that would be much better as live-action due to relying so much on visual representation. Performances were fine with the exception of one actor being way too over the top but other than that. The plot went in circles and the subplots along with the villains were utterly useless.
