Honestly I didn't like much this episode first time I saw it; but on base of comparing with all others programs about the Battle of Jutland: it's excellent. The information is condensed but enough to let the spectator following all the stages of deduction process. Without losing time this episode details both tactical and technical reasons for the amazing casualties of British Fleet: battlecruiser concept and design, importance of signals and visibility, necessity of knowing ranges for aiming the guns and spotting splashes to correct shots, shows procedures for ship's damage control, explains the nature of cordite explosion and propagation of flash; obviously there are questions about decisions of Vice Admiral Beatty including attack without support and the order to firing quickly trying to compensate less accuracy. Like many other programs it shows the only existing WWI Superdreadnought; unlike other programs we can see how it had worked all safety systems, interlocks, doors and hatches between magazines, barbettes and turrets. Finally it brings two different explanations according to individual opinions of USA and UK Specialists; there's not one only conclusion: the results of analysis may change for each individual person. Two critics: I hate the use of small cruiser's GCI views representing battlecruisers; also the idea of magnifying a cordite magazine explosion comparing it with that nuclear others only shows less knowing about A-bomb (and H-bomb, of course).
