As far as I am aware, this comic is in one of three parts.
One part is taken from the perspective of Adrien Brody's character "Royce", one is done from the perspective of Alice Braga's character "Isabelle" and finally the 3rd part is an official comic sequel to the predators movie. I may be wrong, but reading on other fan forums this is what i have gathered.
Amazon shows in "look inside" section of this comic, the Royce story, however when i ordered this, i got Isabelle's side of the story version so i'm not sure what Amazon are doing there!
Basically, if you enjoyed the movie, then this is pretty much the same thing but from the Isabelle's perpective.
Personally I am a big fan of the Predators franchise and still thought the movie was just "ok".
Unfortunately the same applies to this comic version, as it only adds a few extras to what you wouldn't have seen in the movie; e.g. you find out a bit more of a back story to Isabelle's character and when the Predators abducted her to this Game planet.
And to be honest that's pretty much all this comic book adds.
Again, as i mentioned, as it only comes from the perspective of Isabelle, its not exactly a straight movie to comic adaptation, so everything that happens in the film isn't depicted in this comic! There isn't much to see in terms of Predators action either!
My advise is to stick to the other predator comics, especially the Omnibus editions, as you get a lot more value for money.
I hope this sheds a little more light into what you may think about purchasing.
Overall, like the movie, I was underwhelmed by what this comic had to offer.
