I don't see wanting him to recapture the magic of the Smiths as demanding a recreation of the Smiths. A tune here and there might be nice, but as he no longer works with those who can supply such things on a regular basis he tailors his poetry to fit, or, as happens repeatedly on World Peace, not to fit.
When you buy a Morrissey album you expect certain basic things. That wonderful voice, original ideas encapsulated in beautifully constructed words, and a hook. On World Peace he supplies the first, but there is little evidence of the others.
I've just wandered into to town listening to it in its entirety for the fifth or sixth time. The songs that have verses don't have a chorus, and the songs with a chorus lack verses. Staircase comes closest to being remarkable, until the nine syllable title gets in the way.
I dare say there are Paul McCartney fans who heard Mull of Kintyre for the first time and thanked God he had at last moved away from Get Back, Helter Skelter and Back In The USSR. It doesn't make them right.
Great artists rarely eclipse the music that made them famous. In fact, I can't think of a single one. There was a time when Morrissey seemed like he might, and there have been flashes of brilliance. Just not recently. He's been treading water for a decade. Now he is up to his ears.
