I have some better pics for you guys. I shamelessly stole the pose from how to be a poser. Not an easy pose to get him into, but the body is a lot more solid than any of my other sideshow figures and has better range of motion. It still not quite Hot Toys level, but its a big improvement imo.
The tailoring is great and all the accessories are well done. The eye paint is strange, but I don't really notice it much in hand. Shows up more in pictures.
I really like the packaging. The foam figure protector reminds me of Hot Toys DX figures. Its a very nice and welcome touch.
The stand looks nice, but the figure grabber is pretty difficult to use and the arms for the floating speech bubbles and Headpool could use some more length and a little flexability. The speech decals work, and is long as you are careful you shouldn't have too many problems with them. Magnets or that plastic you moisten to make stick to a surface might have been a better solution though.
Overall I'm impressed with this figure and he looks fantastic. That said, given the price, he's not for casual fans. In my opinion, without Headpool he's not worth the money so if you can't get the EX I'd be looking for a discounted purchase.
Enough of my prattling. Here are some more pics.
And lastly, Deadpool sixth scale vs premium format, with Gentle Giant's Squirrelpool.
