These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Nightmare Fuel: The American pilots trying desperately to get up in the air while their base is under attack. Most of the planes are blown to pieces before they make can begin their takeoff roll. One plane is sent skidding sideways along the pavement, making a nightmarish screeching noise as the fighter bursts into flames.
Vindicated by Cable / Vindicated by History Buffs: It was a box-office flop in the U.S. and for the most part, critics didn't like it. But it did pretty well in Japan (eventually breaking even), the expensive special effects shots were convincing enough to be re-used for over a decade(Toshio Masuda even reused most of the Pearl Harbor attack in his 1982 war epic The Imperial Japanese Empire) , and if you need historical accuracy more than you need character-driven drama in a film, this is a good go-to. After the 2001 film, Pearl Harbor, proved a boring and badly researched flop, the reputation of this film as the best dramatization of the attack grew still more.
When you watch the movie today, modern viewers should take a moment to realize that this was long before CGI. All of the effects shots were done with physical models or real planes and ships.
The Woobie: Plenty to go around in Oahu once the battle starts.
One scene features a young Japanese or Japanese-American (a substantial portion of Hawaii's population included immigrants from Japan) messenger delivering General Marshall's telegram to Fort Shafter. The Sergeant signing for the message shares a long look with the obviously terrified boy, who is part of a population who are in for a very ugly time.
Stoic Woobie: Admiral Kimmell. Once the attack is in full swing, a machine gun bullet breaks the window he is standing in front of and strikes him in the chest. The round is spent, not having enough energy to even penetrate his uniform. He feels it would have been a mercy if he had been struck dead on the spot. Both the incident and Kimmell's dialogue musing on this are Truth in Television.
