One of mine is La Scala dvd with Bolle and Zakharova -- memorable for exciting visuals and an exceptionally lame and silly ending.
This is a scenic rather than a dancing memory. Odette has fled.. Siegfried wrestles with von Rothbart, who does his cape-waving routine quite effectively. Siegfried drives Rothbart away, but, falls exhausted.
In comes a most impressive flood of white smoke and undulating parachute cloth. It submerges Siegfried, who struggles upward and falls back down again (rather like a salmon migrating upstream, come to think of it). He's clearly drowning, and the effect is powerful.
Odette returns to the stage having changed from tutu to fairly plain, white princess dress. Her reappearance drives away the flood. She waves her arms in Odette's familiar swanlike fashion. but she then notices she is ... no ... longer ... a ... swan. She's a human. Love conquers all in a brief finale of smiles, promenade, and wedding-cake pose as curtain falls.
The drowning effect is spectacular. Odette's rescue, on the other hand, seems like a last-minute addition (courtesy of Disney) to fill some time before the curtain falls and to make the more sentimental memberse of the audience go home happy.
