In a single word...UNFRICKINBELIEVABLE!!!!!
Hasbro has really improved upon these mini-figures this time around. More articulation, better paint applications, sturdier plastic, better detail, etc. etc.!!!
Commander Gree is the only figure with a minor complaint. They did include the silver paint on the helmet with this version...but they used too much because the green stripe running from nose to chin is missing on mine. Still, the rest of the figure makes up for such a minor imperfection.
As for the rest of Wave 2, they're on layaway, so I haven't seen them loose yet. However, a quick glimpse of them in the packaging suggests the following:
Better paint application/detail
Sturdier plastic on the lightsabers (Aayla and Yoda's blades are perfectly straight as opposed to the drooping of General Grievous)
