These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Critical Dissonance: Like most of Puccini's operas, Turandot still sells out at the box office, but at least one major critic, the musicologist Joseph Kerman, is not convinced: 'Nobody would deny that dramatic potential can be found in this tale. Puccini, however, did not find it.'
Esoteric Happy Ending: Not a few viewers seem to interpet the finale that way. Really, a Happy Ending literally minutes after the best person in the whole opera killed themselves, doesn't look too convincing.
Tear Jerker: It's a Puccini opera, what else did you expect?
