Papo makes a better one:
I got the Papo T-Rex, Velociraptor, Spino, Pachy. I still need the Para and Trike.
I do like Papo's level of detail (especially when they include the well-hidden hinged jaws), but they play fast and loose with scientific accuracy. Now, I own several Papos (including the velociraptor, which I love), and the allosaurus is one of my favorite dinosaur toys ever, but I think of them as the "Hollywood Monster" versions of the species depicted.
I really would have liked the JP-inspired tyrannosaur, but it was sculpted in a position that a T-Rex's skeleton could not actually achieve. I can forgive basic stylistic liberties for the most part, I can forgive a lack of feathers on the raptors, but that t-rex pose looks almost as ridiculous to me as if they sculpted apatosaurus as a biped.
I would forgive such a posture if they were going for the 1950s sci-fi look, but they went to so much trouble to give us a JP rex, why in the name of god didn't they replicate the stance? It's not like it couldn't be balance on two feet, because the aforementioned Papo Allosaurus stands beautifully with his tail elevated an parallel to the ground.
