The episode revolved around the crash of the Byzantium (referred to back in series 4 by River Song). The episodes were very entertaining and arguable the best of this series to date.
Whilst the story progressed, you were also given clues about who River Song is, aswell as finding out a little more about the "cracks" in time that seem to be appearing everywhere the Doctor and Amy go.
Well, I will not go any further on the story as it is quite long to describe. But know this....
Doctor Who is definitely back at its best!! 9.5/10
