After finally having Primal and Megs, I have one thing to say:
Woah.
Those toys feel PREMIUM in and out. Nothing feel cheap. The paint work is perfect. Everthing feel solid. Joints are tight. Plus both are what we may call "mini masterpieces". They are also to scale with one another. A first in the regular lines since BW is a thing.
Transforming Primal was easy enough. Plus I love the fact that you can do the "normal" gorilla, or the standing one. Megs was damn scary to transform. Because everything is so THIGHT, I was affraid a few times to break something. Especially the torso clip... But once the groove was on, transforming Megs was a pleasure and it resulted in a PERFECT T-Rex that is ridiculously articulated.
Overall, the beasts in the Kingdom line are absolutely fantastic. I planned to skip on Cheetor but now I have to get him. Paleotrex too.
