Actually I tend to find Aida tedious and much prefer Otello and Falstaff.

Tosca is schlock, but a good Scarpia (Leonard Warren comes to mind) makes it tolerable until the last act, when, of course, he's dead.

Boheme, OTOH, always, always manages to reduce me to tears, unless the Rudolfo is just plain awful.
