This series has interesting characters and a compelling concept, and it moves forward at a leisurely yet engaging pace. However, the MA-rated components (mostly F-words and some sexual content) and the progressive content seem inorganic, and they detract from what otherwise be very engaging and entertaining. Perhaps series with a TV-14 rating aren't moving the dial any more, so the producers feel compelled to toss in a boatload of gratuitous F-bombs, progressive sexuality, and (as one example) creepy conversations among senior adults about sex toys. But, to me at least, these elements seem artificially added in order to merit that "coveted" rating of MA. This series could easily have been TV-14. It would have been the better for it, and its audience might have expanded. Aspects of it are still quite enjoyable, but on the whole, "Only Murders in the Building" strikes me as a great concept sullied in pursuit of vulgarity.
