I think it was pretty obvious that by 1957
Chuck Jones was chafing at the bit. Even he, I suspect, was getting bored with the old Bugs/Elmer, or Daffy/Porky(or Elmer) or Sylvester/Tweety formula, and I think this is the short which proves his claim that WB made cartoons for themselves, not for kids. How many kids, after all, do you think could name the four operas of Wagner's Ring cycle in order? And how many adult classicial music fans, for that matter, could tell you that apart from the infamous 'Kill the Wabbit' chorus, there's not much of The Ring in this cartoon anyway (though it is all Wagner)
A sea change was happening, if not at Warner in general, then at least in Jones' head. Whereas Tex Avery was happy over at MGM to be a madcap, splastick loon forever - Chuck Jones clearly had developed designs on being an artist (horror of horrors). As a result, most of this cartoon is still going to zoom straight over everyone's heads, whether they're kids or adults. I suppose this levels the playing field, at least. And it should be mentioned that Michael Maltese was clearly Jones' partner in crime here.
This is very often regarded as the best thing that ever was made. I don't think it is. I think it's very impressive, but I don't think it's quite that good.
I just watched it repeatedly, trying to figure out what the hell people see in it to elicit that response, and I still don't understand. The art direction and backgrounds are often fabulous. The music is obviously spectacular. The opening sequence almost rivals Fantasia's 'Night on thr Bald Mountain', of which it is an obvious parody or homage - but there's no getting away from the feeling that they were running out of ideas for Bugs and Elmer, and making it intellectual - while undoubtedly startling - is still sort of new skin for the old ceremony, except this time it just isn't very funny.
Not that there's anything wrong with that. MY favourite WB short, Ding Dog Daddy, isn't funny (anymore) either (see my review if you like), but this one doesn't have the virtue of being inadvertently poignant.
It seems odd that I've spent so much time criticising a film which I've given 3.5 stars, but most of its reputation is deserved, and you can read a gazillion reviews telling you why it's the best short ever made. I'm just pointing out the chinks in the armor which knock that half star off, for me.
If I had to find a word to sum up 'What's Opera Doc' it would be 'clever'. It's clever. It's not funny; it's not poignant; it's cerebral. It absolutely belongs in your DVD collection, but don't just automatically buy the line that it's the Citizen Kane of of animated shorts.
Or perhaps you should, because my feelings toward Citizen Kane are much like my feelings toward this. It's perfect, but there's still something ineffable missing. Maybe it's heart.
