Is this the complete sixth series?

Yes. It covers the full 2011 series with Matt Smith, including the Christmas special, rather than a shortened volume.

Will it play on my Blu-ray player?

It is a Region 1 Blu-ray, so it plays on US and Canada players. Players set to other regions will not read it.

It helps. The Silence and River Song threads build directly on the previous series, so starting here loses some of the payoff.

The episodes are the same; the Blu-ray gives higher resolution and is the better pick if you have a high-definition setup.

It carries the usual behind-the-scenes material and commentaries for the series, though the extras are lighter than later box sets.
