I noticed that on my Biggs and Vader as well, the bubbles aren't well-attached and on one of them the glue had turned white on the right side which also looks bad, I predict bad things from that.
Not only dull but at least on my Padme, the bubble wasn't glued on very well. I usually keep one or two carded from each series but may abandon that.
6" Fett is going for at least $120 right now!!! I like mine but it would have been better served with a more rubbery plastic for the belt pouches. As is, leg articulation and posing is severely hampered.
