I love how ridiculous Concrete Jungle was. At least the predators there are treated as hunters...
Predator 2: Look how fun and silly we can get!
Concrete Jungle: Hold my beer...
I'd rather see Concrete Jungle done as a movie than The Predator. With CJ we know how dramatic, over the top and ridiculous it is from the very beginning. Most importantly, it's fun. The Predator for me and looking at the reviews, for many was not. When will these guys get it that Suburbia is a horrible setting for a predator. And a dark forest does not make something automatically scary Shane....
Pick a tone and stick to it. Pick a good setting. Respect that the predators are hunters. Always keep a bit of that tribal aspect. Show new weapons and tactics the predator uses. Keep the story simple and logical, just spice up the substance.
Concrete Jungle is a really good example for me personally. It's on over the top and on the edge of being acceptably fun, but all the elements are combined well. IMO it works.
