No one has been able to get Hoth Han right in the post-vintage era, and few Death Star/Star Destroyer/Death Squad Troopers were good, either.
Others upon which I still agree:
4-LOM (the "wrong" one, the Gand huntsman, the non-droid)
Han trench coat
They've been getting a little better lately with some, but most are too scene-specific to me.
