Ismene Brown, a great supporter of the Wright versions, did a great interview with Sir Peter Wright about the authenticity to the original production in his production. Unfortunately the link for it on the Telegraph's website seems to be down--maybe because it's old (it's from 2000) but maybe it's just temporary.

(For instance he calls the reconstructed Garland Waltz in Mariinsky's Sleeping Beauty too boring for modern audiences--I love it partly for how it's simple and repeated and grows from there--and he claims likewise the original Snowflake choreography would bug modern audiences. Similarly he doesn't like the earlier more faithful Waltz of the Flowers--which I prefer, and says the carefully reconstructed Grand Pas De Deux detail of the Fairy gliding en pointe on the cavalier's scarf never worked which is why he removed it shortly after the first DVD was made--yet I LOVE that detail--which we have a picture of in the original 1892 production, etc).
Basically a fair bit of dance was kept, or they tried to stage authentically, for the original 80s Royal Ballet production by Wright (the patters, if not steps, of the Snow Scene and Waltz of the Flowers, the dolls dance in Act I, the Chinese dance, and the Grand Pas in complete), but by the time he revised it in the 90s MOST of that was thrown out.
I'm very mixed on this production. I love a lot of Act I. I don't care for the new story ideas like the Nutcracker/Droselmeier connection even if they were in the original Hoffman (the ballet is adapted from Alexandre Dumas, pere's simplified adaptation of the Hoffman anyway), I also LOVE all the reconstructed bits, even the somewhat offensive Chinese dance, for their authenticity. I do not like ANY of the changes he made for the more recent stagins--as you can see on the recent DVD--like having Clara and the Prince dance in so many of the divertissements (why?) and I miss some of the charming and more goofy elements--like Mere Gignon. I also think the Kingdom of Sweets colour scheme (pink gold and beige) looks awful on TV although I suspect it probably works a lot better in person. This is all in reference to the 1980s DVD, I have a lot less affection for the revised version.
I do find it a bit odd that Wright set out to stage it as close to the original as possible--and then made so many changes, but I suppose this is his prerogative.
