Opinion seems to be the new extras are thin but pretty cool all the same (they are only 30 minutes each for each film) but if you have the previous set theres no need to buy this. The extras are really just a bonus for those that don't have the films or want one or two of them individually. Theres no doubt going to be a 4-film set this christmas, so maybe then we'll get all the extras from both sets plus some new material.
