OK, here's some initial feedback on my LUKE Ex:
I love this figure. The excitement has made me bias. Overall, FOR THE PRICE, its great. The sculpt is fine in person, honest.
Here's what I don't like:
The arms only bend to 90 degrees -- can't put his arms akimbo.
The hands are not as moveable as say Dragon. And they tend to pop off when trying to pose them. Its good for swapping hands, not so good for posing.
The pants tend to pinch in at the hip joints -- definitely need to stuff some TP in there to fill him out.
Last thing, the head is a bit big, even relative to the other Sideshow figures I have. Actually, he's quite tall for a "short body". He's nearly as tall as my James Bond figure. Not a big deal really if he's in scale to the other Star Wars guys but we'll see...
That's the bad bits so far. If you're a customizer, this figure will look a lot better with a Dragon body no doubt.
However, these nitpicks aside, I am sooooooooo happy with him. A really great product.
