I loved Leia as Boussh as a kid for probably the only reason being that she was badass looking. Leia finally looked less like a whiney girl and more like she could handle herself... Probably my weird perception as a kid I guess since Leia was fairly tough in the movies. Go figure.
The original figure was great though... The removable helmet rocked. The gun was awkward and not really practical looking, and obviously anyone holding that in the vintage line (holding it like a gun anyway) looked kind of goofy. I always hated that about the vintage articulation, even when I was young. Articulation's always been a big deal to me I guess. But it was still really cool. I wound up breaking the handle off the gun and I think a rnadom Cantina dude I made is now walking with it like a force pike.
The modern incarnations are so-so... The POTF2/SOTE figure was a letdown. The molded-in detonator sucked, and the articulation was lacking. The sculpt was nice though, a big update from the original, and so that aspect was kind of neat.
The Saga figure was a pretty great update though, and the fact she could now holster the detonator on her belt or hold it was simply great. Hell, it was just great getting a separate Thermal Detonator as an accessory. Her articulation was updated substantially, the scale was better, the gun and helmet were better, the sculpt was much sharper...
However, the articulation is sub-standard nowadays, and I think softgoods would go miles and miles with a figure like Leia disguised as Boussh (assuming all the other good stuff like the detonator, etc., remain in tact). This is a figure I'd certainly like to see updated despite getting what many would consider an acceptable final figure. I agree, I could live without it, but I'd certainly not turn my nose up at a "definitive" version to replace it.
