Finally opened up one of these today and I'm shocked at what I like most about this set... which is...
Savage Opress

I never got the original, so I gave Maul's lightsaber to Savage and gave the Nightsister saber to Maul. Totally love the set now! I was really shocked that I gave more attention to Savage than the other figures - and I'll explain why.
Nightsister is very well-executed for a generic Nightsister, it's a definite hit. Not anything extraordinary or overtly cool (I kinda want a Talzin now that I think about it, but I'll pretend this is her), but very well done.
NOW for the elephant in the room (seriously, Maul is a giant compared to Savage, which really surprised me).
I'm so disappointed with the Maul figure.

I really wanted to like this figure, and I had such high expectations! But seriously, not giving an articulated waist or wrists to an otherwise almost-perfectly articulated figure is so downright distracting! It's the fact that it's just
almost there that distracts me - granted, I'm grateful Hasbro went all-out with his legs, but it's so hard to achieve any cool poses with the missing points. And I really don't like the headsculpt either, I don't think it looks much like Maul from the cartoon. Being that the Maul figure looks downright goofy and the Nightsister is just alright, I loved the Savage most of all right off the bat.
A+++ for concept.
B- for execution. Granted though, this is a very nice set with much value, but, as a collector item (as in for a collector who expects TVC standards from everything, unfortunately) it's just okay.
