Indeed. That, and he has a pretty bad habit of starting story arcs that look like they're meant to last at least several episodes to come and define their own part of the season, but are cut disappointingly short without living up to their potential as the show flits onto something else and does the same. (Demon Dean in SPN Season 10, Sally's brother becoming a ghost in Syfy Being Human, to name a few examples.)

Plus, there was Carver's habit of, in spite of the above; introducing silly, petty and needless story arcs rather than focusing on greater storylines. (Like, say, Who Killed Ezra) And I think his desire to refocus on Heaven and Hell and dismiss Purgatory of Gamble's era just didn't work out, since the angels and demons have been milked for most of their big stuff with the Apocalypse.
