This is a very well done TV movie; criticisms that it only features one of the units involved are not really valid. The movie chooses to focus on two levels; that of a single battalion (in this case the Royal Regiment of Canada from Toronto, not to be confused with the Royal Canadian Regiment), and also the highest levels of command. Those not familiar with the command structure of the Canadian Army in WW II may be briefly confused but will be able to pick out the chain of command by context clues.
Working within an obviously limited budget, this production goes above and beyond in presenting an interesting, and accurate if slightly fictionalized view of the politics behind Dieppe as well as the view of the Raid from the soldier's POV. Blue Beach is recreated in great detail. It is unfortunate the other parts of the raid were not recreated, but they weren't necessary for this telling.
Be sure and read Brian Loring-Villa's book in conjunction with this series.
DVD version has a fascinating 1962 documentary with interviews with many of the key players on the real raid. See also my review at amazon.com regarding the DVD for additional info.
