I dunno, I thought they did a pretty good job with Primal. No big gaps, everything curving into each other nicely. That's why I'm so surprised that Dinobot looks such a shocker in beast mode. Frankly....
...that looks just crapBW fans deserve a bit better for their money. I'd accept this alt-mode from a legion-sized figure or maybe even a deluxe, but not from a super expensive MP figure.
Hmmmm..... I am a Grimlock collector. If they release a Grimlock version for, say, $80-$85 I'll pick one up
