Diddly, I agree with you wholeheartedly actually. I love the upper body sculpts on the BD figures, and I think they're good for neutral and action poses. They are passable at the least, and pretty good in that regard overall.
The legs are a killer though. If the figure can't stand, it's no good to me, and the BD sadly cannot stand at all. This ROTS one can't, my red ones from AOTC can't, and I'd say the worst of all are the cream colored ones from AOTC. I tried putting them in my E1 Gungan scene up on a high shelf (so I don't have to look at it TOO often
), and they nosedive off that shelf constantly... to the point I've made them "deads" on the field rather than tried to have them marching along with the E1 droids.
Hasbro could be using a sturdier plastic in the legs, at least. It's really to the point it's sort of insulting that, even with stands, a figure can't stand. A couple padme's are the same way too, which sucks. Naboo Celebration's one of those culprits for me.
