Sculpt--3/5
I'm tempted to give this figure a 2.5/5. It's not a bad sculpt detail-wise, it just seems like this should be a normal carded figure. That is, there is nothing really "deluxe" about this figure. He's practically stuck in this one pose as his articulation can only do so much to vary it. I guess he does fit in with all the other 'attacking' Jedi figures we've gotten, so if you like those, you'll like Deluxe Mace. However, the more and more I look at him, the more he looks like he should be on a surfboard.
The thing I hate most about this figure is the headsculpt. It's actually not a bad headsculpt and has a passing resemblance to Samuel L. Jackson. The only thing is...he looks very happy. This is not the right expression for a kick-butt Jedi like Mace Windu. Looking at the package photos, it's easy to discern that his eyebrows are supposed to be meaner, but the actual toy's are not.

Articulation--1/5
Mace Windu has seven points of articulation: neck, shoulders, left elbow-cut, waist and hips. I'm sorry, but this is just craptacular. The articulation does practically NOTHING to change Mace's pose which is a major disappointment. This figure NEEDS a ball-jointed left shoulder. That joint alone would have made the articulation acceptable, but how it is now, the articulation is just piss poor. Turn the shoulder too much and his sleeve magically defies gravity. Turn his forearm too much and it looks like his arm is broken. What else can I say? This articulation just wasn't thought out too well.

Features--2/5
Mace Windu has a Force Action left hand, in that it has a small magnet in his left palm. The magnet is extremely weak, however, and can barely help hold his lightsaber, let alone Force-attract it.
Mace's other feature is his projectile-shooting right arm. You can shoot a fireball (a Force-blast), or you can shoot a big claw-like thing which is supposed to represent a Force-push (used quite a bit by Obi-Wan and Qui-Gon in Episode I). I can deal with the fireball thing, but the Force-push projectile is just an insult to my imagination. I would much rather just flick the Battle Droid with my finger than use this crap. What would have been cool would be if they had put a powerful magnet in Mace's right palm and another in the Battle Droid's chest. All they would have to do is have the same pole (north or south) facing forward on each magnet, thus repelling each other when they got close enough. The magnet idea in these new figures is very cool, I just don't know why Hasbro doesn't exploit it as much as they could.

Accessories--3/5
You get a blast-apart Battle Droid, a Force blast effect, a Force push effect, the Battle Droid blaster, and Mace Windu's lightsaber. The Battle Droid is alright I suppose. I've never opened a Battle Droid before so I can't really comment on how it compares to 'normal' Battle Droids, but it seems to be the same, detail-wise. The Battle Droid is articulated at the head, neck, shoulders, and hips. He has a removable backpack, his head comes off and he separates just below his chest section. He has a hard time standing up, mostly because his gun causes him to be totally unbalanced. The blaster has a metal slug in the handle so certain figures can Force-pull the weapon. The figure would need a very strong magnet though, and Mace's just isn't strong enough to even hold the gun. Obi-Wan Coruscant Chase can hold the blaster rifle in his magnet hand though. There are two different Battle Droids that come with Mace. One is the normal beige-ish color and the other is the red, maroon-ish colored Battle Droid. The red Battle Droid is found in later shipments of Deluxe Mace and is pretty much exactly the same as the beige one. The red one does seem to be made of stiffer plastic, which makes him seem more stable.
The Force-blast effect is decent as a projectile for shooting down the Battle Droid and resembles a fireball. I picture Mace saying, "Ha-do-ken!" when shooting the fireball out of his hand (That's from Street Fighter II). The Force-pull effect is just plain unimaginative in my opinion and resembles a big claw that goes around a figure to "push" them away.
Mace Windu's lightsaber is the best accessory of the set and is made of metal. It has nice gold trim and has handle grips reminiscent of lightsabers from the original trilogy. Mace's hilt is probably the longest handle I've yet seen (not counting Darth Maul's), but I believe it's accurate to the movie. Of course, the purple blade is removable.

Paint--2.5/5
All the figures I saw had bad paint jobs, especially around the collar. My figure has a pretty well painted collar area, but after opening him I found a huge smudge of brownish-red paint on his butt.

Overall--2.5/5
Surfin' Mace Windu is a good basic figure but a poor deluxe figure. I really feel like this could've been a basic figure--perhaps then I wouldn't have been so disappointed. And I still can't get over how happy Mace looks; it just makes this figure less cool than it is. I wasn't really looking forward to the screaming Mace Windu figure coming out in the next wave, and now my hope for a good Mace Windu is dwindling ever so much more.
