Chuck's Reviews Transformers Studio Series Optimus Primal
 

While I think this is a good figure, once I got over the size shock after opening the box, Optimus Primal just isn't worth the price. I feel the transformation, while simple, is overly involved to try and drive up the parts count. The Mainline Voyager of Primal handles the leg transformation better. The accessories are nice, but I don't understand why they weren't included with the respective figures in the first place. I can only recommend Primal if you find it on sale.
