Romeo and Juliet is also my favourite one. I've got various recordings: Muti, Previn, Maazel, and the last Gerviev with LSO. I've seen two productions of the Royal Ballet and one of the Bolshoi (in cinemas).
I like other ballets, but not as much as Romeo.
i take the oportunity to say that I don't like Minkus (many ballet dancers are very fond of him).
