Honestly, most people can't really pose worth a damn, but the newer Predators have way more range than people give them credit for.
Probably 2/3 of the figures in the image in
>>7488034 are from old, outdated bodies from maybe 2012-2014. They had single hinge/swivel elbows, no real torso articulation other than a swivel at the waist, and even stuff like the double knees were more limited.
Most of the newer Predators starting at the AvP figures in 2014 had much, much better articulation. You can get some pretty good poses out of them, but most people are kind of retarded at posing, and don't do anything other than a stock/standard pose.
The only real issue left with NECA Predators is that the ab crunch needs to be deeper to allow proper crunches, or the joint actually needs to be lower, like in the stomach. They also really, REALLY need to work on the ankles, because they're still using the same ankles as they did when the line began in 2010, and they severely limit any real dynamic standing poses.
If they could fix that, they'd be some pretty incredible figures.
