Three seasons into "Only Murders in the Building," the sprightly mystery comedy has banked enough affection with its fans to make the main case less essential to our enjoyment than what's happening in the lives of its citizen detectives. If you've discerned the show's common patterns and tells over the past two seasons, which happens to nearly every series in its third go-round, you may even finger a culprit weeks before the finale.
Even if that's the case, who cares? The killer reveal is always simply the cherry on the sundae, or the marmalade on the Pickle Diner's off-menu sandwich – it's a wonderful bit of sweetness added to something that's substantial on its own. And hanging out with old friends for a few weeks is the real grade-A meat and dairy this show provides.
