I've been looking forward to this figure, and I'm happy that I bought him. As for my specific opinions . . .
The guy is a statue. His inner robe is a single cylindrical piece, it's hard to get at his legs. Which are quite stubby because there are only stumps under there, just like the Jar Jar Binks figure. But OFT is better than JJB because his solid body is not leaned into that awkward pose of JJB. Even though Hasbro took a shortcut with the legs, I'm pleased by his blue feet and minor ankle detail.
The robes are fine, considering they are not cloth. I like the touch of two strands hanging down the front, and the rest of the robe is nicely sculpted without being too chocolicious. The buttoned undercoat is nicely detailed.
He has a great head sculpt. Not much room for variance in paint jobs, since the only things painted here are his teeth and eyes. I'm glad to say both of these features are well done in my case. I like his blue head, and I see they faded it out a bit on his front tentacles.
The tentacles are cool. Even with 2 hanging down in the front and another 2 in the back, they do not prohibit the head from moving, and I like that. The only problem I have here is in the rough spot on his front left tentacle. It appears to be a bad break from the mold, but that's just my guess. I'm not sure how prevalent this is, let me know if you have this same problem.
And how about his arms! Articulation at the elbows AND wrists, now that I like. Even with the robes, I'm able to move his arms up and down, and the poseability of the wrists allows for fun senator playing action. I currently have both arms raised, palms parallel to the ground. Depending on my mood, he's either doing the magic fingers or he's shooting force lightning.
Accessory is alright, a senate cam droid on a clear stand. I like that it's movie relevant, no need for electro fx here. But I do think the stand could be higher, the droid's antennae is only as high as OFT's teeth; I would rather it stand taller than his head. But it's no big deal to me.
Overall, I'm not too big on the statue body, but my love of his arms and head redeems that. I give him a very solid B+
