One thing that gets me is that they have managed to make chewies face look like he does in the OT yet lucasfilm made him look completely different for ROTS.I never understood how they could get the face so wrong in ROTS.

The carbon freezing plot is bloody ridiculous though and completely ruins the danger of Han getting frozen in ESB. Lando says that if they put Luke in there it might kill him, so Vader tests it out on Han. Why would he have bothered if he knew it was a safe procedure?

Vader's line implies otherwise, as I've explained before. And the danger can be explained with the facility being crude.
