I held out as long as I could but in the end I caved and looked up the spoilers.
My knee jerk reaction was not to like it but within seconds I found myself warming up to most, not all, the film was brining. It really will depend on the execution.
If your a Yautja hardliner, like I was when I was younger, your gonna hate this film with a passion. But really the Yaujta lore is not that ingrained in even the comics. Most do not touch on that subject at all, sticking to the movies' habit showing hints. Most novels post the dark horse ones make up their own, South China Sea being a good example.
As for the whole Predators using DNA to improve themselves, I'm shore that was something in the old Predators script. The Super Predators looked different because they were genetically modifying themselves with their preys DNA. With that unused idea plus the supposed blood feud mentioned in that film and the deserters in this one, one could assume The Predator is building on what was hinted at in Predators as well as keeping in line with 1 and 2. It would seem that Predators as a race are collectively going in for "improving themselves" and our old honour hunters are the minority.
I'm gonna have to see this to really judge it but it could work, sometimes a radical change can be a good thing if done right. Or it can be a total f##k up who knows.
Edit:
Actually, I was just thinking about the whole premis of the film and then it hit me. A person who is seen as a lesser beats a superior foe due to his unique talents.
Both the human military and the villinus Predator seek conventunal pefrection through physcial and technological improvement. They embody the sterioticpcial Alpha ideal. But in a David and Goliath twist, the Ultimate Predator is no felled by a superior foe, for none can hope to match him, but by something it and even we humans would offhandedly consider infiror or flawed.
Thats actually a pretty cool idea that plays against expectation of what a Predators film normally is about.
