Maybe I'm getting too technically here compared to how it was composed, but it seems symptomatic of how we've decided melody and accompaniment means melody and bass line. Like, the bass line is not just accompaniment in this song! It trades off with other instruments as part of the melody! So if a cover decides to focus the guitar in the opening where the bass is the actual melody, they've probably misunderstood the song.
And I probably should say I can tell if a cover is "good". After all, many covers that screw this up are still good. They just don't do the song true justice IMO.
