If you like the effects in the 2011 version, you are a fan of 1997 effects, a 1999 jabba, and a 2011 dug thing
Edit: as well as perhaps a 2011 flashy carbonite effect, Ewok eyes, and a door. Lot's of modern effects to get excited about! I think they should have held off on the blu-ray until 2014. So much more could be done with doors now that technology has evolved even further.
