As far as advice goes, I'll just quote from my review:
The Jason of F132K9 is an amalgamation of damn near every portrayal of the character since part two, though young Jason makes a brief, almost unnecessary and slightly ridiculous appearance at the very beginning of the film. His face throughout is the mangled and deformed Jason found in the first four installations while his dress and overall physical enormity is more characteristic of his latter portrayals when he eclipses merely being a really difficult-to-kill human being and becomes, for all intents and purposes, a zombie. In an interview with Suicide Girls Form and Fuller stated they drew inspiration from only the first three films to craft their new Jason, but to have done that would mean scaling back in intensity what eventually became their final product.
As such, aspects of the Jason of the first few films appear only very sporadically, the most notable being Jason’s burlap sack mask; otherwise we’re treated to a Jason that’s a calculated, emotional, and above all overwhelmingly aware killing machine. In parts two and three Jason was almost secondary in nature, making an appearance only to kill; here he and his motives are the forefront. We’re shown his new home in the form of some entirely unnecessary and ludicrous underground layer, and by extension are privy to a Jason with the sort of depth designed solely to appeal to a mass audience thirsty for outrageous kills.
Jason is an emotional character, and I think Form and Fuller’s desire to separate that from their vision of Jason, due in no small part to their desire to eliminate most of the background concerning his mother, was a mistake. The ending of the reboot, intending to mirror the ending of part two which was dependent on Jason’s love for his mother, was ruined by the absolute lack of believability in its execution. No reason is given for Jason’s abduction of Whitney at first, and her method of tricking Jason is given little to no credence, save for a brief passing mention toward the beginning that is neither true to the mythology nor credible. Jason was shown to be far more intelligent than one would expect him to be, so fooling him by displaying a locket with an old picture of his mother should have done nothing. In part two the character of Ginny actually attempts to emulate his mother’s appearance, first by putting on her old sweater then by actually comparing her hair to the desiccated head’s. Their desire to make Jason an unstoppable killing machine with the expected intelligence of someone who is not a deformed and mentally challenged monster indeed worked, but as a result the “magic” of the character, at least how I see it, ended up becoming one of his victims.
