The episode was the ultimate fanwank, not only does the carbon freezing chamber looks and sounds exactly like the one in ESB (and is also run by Ughnaughts, who now seem to have a monopoly on carbon freeze), but the jail looks like the Detention block of Star Wars, security cameras and all.
And of course they used the shuttle disguised as a transport for cargo to land on the planet. They should have made one Battle droid say "fly casual" in case someone missed the reference.
