My interest here is of course "diorama building" to have everything seen on the screen (or most of the stunningly visual and speaking roles in their costume changes represented).
I don't purchase "improvement" characters like the umteenth Luke Tatooine, Vader, nor Jango Fett.
I understand their role in "selling the line," - primarily to newbie collectors who are just getting their first Vader or something like that because they were too young for "ages 4 and up" before hand, so it must be available on the pegs now.
However, for the "collectors' spots" in the Hasbro lineup, I don't think we yet have a Greedo figure with a working holster for his gun. You could argue that this is a new way to release an improvement. #%*! if I'd buy it, however. I own enough Greedo figures - but yes he's far more recognizeable than Nyrat Agira whom I like because she looked great in a thong, and she represents the fact that Coruscant is NOT a more alien world, but a human-centric one and Club Outlander represents the human nightlife in a galaxy far, far away - if only to contrast that from the Mos Eisley cantina. This makes me like the Mos Eisley cantina even more - though I have a strong desire to create dioramas that illustrate the difference between The Core and the Rim Worlds.
Is Bail a line-killer and representative of the failure of that 2008 wave? No. I don't think so. However, his speeder pilot outfit (though best a pack-in with the speeder vehicle itself) is from an action scene where the character was armed and would be accurately portrayed as (at least a little bit even) more fun for kids than his robes he just walked and talked in. As for his "cross armor" he wore in the Senate? Well he is a Senator and that's a good way to portray him.
