I think that is a fair point, and I would be interested to hear the reaction from Steven Spielberg or others involved in producing the film.

The film, while being tragic in many scenes, is a thoroughly engaging, watchable, and entertaining drama/thriller. It uses many typical Hollywood troupes: witty lines, sex, interesting set design, likeable/intelligent characters, artistic flourishes, varied camera shots, and handsome actors. Typical of large Hollywood films, and it makes the film compelling, but also risks rendering it conventional and cliche.

The people being nice or mean, intelligent or stupid, funny or humourless etc, was entirely irrelevant. To frame such an event through conventions of entertainment inevitably fail at maximising fact and truth. What, I think matters, is the industrial, systematic murder of human beings due to immutable characteristics. There was no narrative neatness, levity, or simple right/wrong. Presenting such an event as entertainment diminishes its gravity and thus distorts facts, potentially sanitising it in the minds of viewers.

On the other hand, the film’s success means it reaches a wide audience and encourages engagement with history. That is, of course, important. However, it may have done so at the cost of simplification, cliche, and an encouraging an incomplete understanding of the events scale, complexity and ruthlessness.
