But surprisingly to me the film got much of the actual event right. The CGI images got to be a bit much (heavy swarms of zeros dodging through battleship row, some screen shots where animators felt compelled to fill every space with aircraft).... but all in all the film brought the story home to me quite well.
What irritated me more than anything was the saluting. Prolific saluting throughout the film. Oders given... everyone salutes. Plane lands on deck, deck crew salutes. And wow.....the Japanese officers must have had severe arm flex and retraction injuries over time!!!!! HAI!!!!!!!
Most vets will know that there is and has been very little saluting on board a ship. Attention on deck can be standard in a wardroom when the skipper walks in, but he usually dispels such custom early on. The rule has been to salute an officer once each day and move on, but even here....it just doesn't happen much. Officers and crew know that such exercises distract from work, attention spans, work details, etc.
A nitpick, but I had to laugh at the frequency within the film.
