The first hour set-up is a bit boring, but it gets much better after that. The bonus features are outstanding and are sufficient alone to purchase this set. Regarding the movie itself, however, I was very disappointing with the ending. Basically, the film ends when Burgess and MacLean defect to Mosocw. Thus, it does not include the remaining 12 years of Philby's spying, nor the eventually unmasking of Blunt. Additionally, Philby's relationship with CIA Chief of Counterintelligence James Jesus Angleton is vastly underrepresented -- particularly as it is germain to at least a portion of Philby's access while he was posted to the British Embassy in the U.S. Lastly, there are several very glaring factual inconsistencies, though the disclaimer at the beginning of the movie acknowledges that the makers took poetic license for "dramatic effect". Frankly, the true story is dramatic enough, and I feel (like a previous reviewer) that this movie was a bit of a lost opportunity to tell the whole story accurately. That said, it still is a decent-enough movie, and worth purchase for the bonus features which contain actual footage of the spies.
