90% Of The Problem
It still won't be a great movie, but it will be more appropriately a movie refelcting of its time, but 90% of the problem is the musical score.
Remove that, replace it with something tamer, the movie will be dated, but okay.
Even just tone down the Sousa score, it will be okay. It just comes blaring thru like that.
I watched Halloween (1978) and not having seen it for a while and noticed the same shrill music piece turned up over and over. The opening piano piece was only played twice after the opener; when the doctor saw the car & Laurie was going out of the house and then at the end.
Im 30 minutes into this so far, and the march has blared thru too many times. Hopefully it won't return, but I suspect it will.
