Pretty accurate in terms of history. I'm not an expert, but I am well read (Layton, Tully & Parshall, Symonds) and I really didn't see anything that drove me crazy the way Pearl Harbor did. The sequence at the very beginning of the movie with the SBD dive bomber landing like a yo-yo bugged me very much. Not possible. Broken airplane and lots of injuries would be the outcome, along with a grounded pilot in all probability. Kind of a turnoff, but in general I liked the film. I also think Jake Weber as Spruance should have gotten more screen time, given that his decisions won the battle, in the macro sense.
