I bought this DVD for the Ruddigore animation which I had seen on TV some years previously. The Hoffnung cartoons are good, but require a certain mindset to find them funny. Gilbert and Sullivan on the other hand always had a good strong narrative structure and Ruddigore, with its burlesque of late Victorian melodrama has both a good plot as well as sublime music. The sound is a trifle odd and has always reminded me of an edited (not every line of dialogue is there, and it is the Toye version of 1920) D'Oyly Carte recording in an empty theatre, the ambiance is a trifle echoey. The animation is stylised but satisfying, the character designs angular but quite acceptible. The way the coming of the curse is portrayed and also the Ghosts High Noon sequence is wittily constructed and I would say that this disc was a worthwhile purchase.
You'll wish you could still get it! There are not enough DVD recordings of Ruddigore, just this and the '82 Brent Walker with Keith Michell as Robin Oakapple and Vincent Price as Sir Daspard... I wish recordings had been made of the D'Oyly Carte on stage....
With regard to the whole disc, I would like to see more British Animation made available; Halas and Batchelor were a significant force in the UK but still get subsumed under the weight of US animation even when the American films are dross.
