I just can get past the "I made imperial poopie in my pants" expression on his face. He was evil incarnate, not Mr. Giggles....
Seriously though...that expression would've been good fo an alternate portrait and have the regular one be a more determined sinister one.
Gets my vote for most underwhelming figure out of the box.
It grows on you though - he's cemented his place in my ROTJ display. I don't recommend people get the DX though - I really have seen very few pics of him seated that look good and it's just a fig that needs to be displayed standing. After a lot of work I found a seated pose that I liked well enough but it was still kinda underwhelming.
