It is one of the best (if not the best) carrier movies ever made*, and you have to tip your hat to the USN for making it so, and James Michener and Val Davies. A whole range of vintage a/c are on display (including spotted Banshees) and great on/off board footage of the two Essex' lent. I'll have to buy it because the footage of Nestor and then Brubaker and Forney, plus quite a few of the locals being shot is censored. I hate that. War Is Hell!
Another American naval show which I thought was very good was the mini series 'Winds of War' with Robert Mitchum. Haven't seen it for a while but I was impressed back in the day when it ran on TV because of the realistic sea battles depicted off Guadalcanal. That would have been models and early FX but I think it worked far better than a lot of stuff that was made a decade or two earlier. The battle where San Francisco got shot up was very intense.
I can put up with most things in TV and movies that aren't of the time except replacing the context with contemporary writing. Walk out straight away (oh, and the haircuts!).
* 'The Final Countdown' will always beat 'Top Gun' for modern USN carrier deck operations action, just wonderful!
