You’re probably not the only one… but I respectfully disagree with you. I saw the movie back in my evangelical days and it put a different spin on the Passion. A lot of evangelicals tend to have a sort of goofed up understanding of the Passion. Seeing Gibson’s movie put everything into better focus for me.
The violence you mention is the means of our redemption. “By His wounds, we are healed.” As an evangelical, I didn’t have a proper understanding of that. But now I do. So the violence was, oddly enough, a major part of it for me.
That said, when I do my annual Passion rewatch, I always stick with the shorter, less bloody version of the movie. Because there’s only so much I can take, you know? But seeing the regular bloody version was an important step for me.
