Born on the Fourth of July: Is Kovic's disillusionment too on the nose?

Okay, so I finally sat down and watched Born on the Fourth of July. I know, I know, late to the party. But, honestly, I came away a bit conflicted. On one hand, the sheer visceral impact of Kovic's experiences, particularly the combat scenes and the VA hospital nightmare, is undeniable. Stone clearly wanted to hammer home the brutality and the neglect, and he succeeds. The acting, especially Cruise, is undeniably powerful. He really sells the transformation. But here's my question: does it feel too calculated at times? The rapid switch from gung-ho patriotism to utter disillusionment, the almost immediate and complete rejection of everything he once stood for... I get trauma can be a catalyst, but the leap felt a bit… convenient? I'm grappling with whether Stone sacrificing subtlety for the sake of a powerful message? That scene where the veterans are protesting and getting brutalized is especially provocative. And what about the portrayal of his parents? Were they meant to be symbols of blind faith, or just… tragically misguided? The scene at the Republican convention where he confronts them is incredibly charged, but it also feels a bit simplistic in its portrayal of their views. I'm not saying the message is wrong, just wondering if the execution veered into overly didactic territory. Am I alone in feeling this way? Or is the film just that effective at stirring up discomfort and challenging deeply held beliefs, regardless of any potential heavy-handedness?
