Only Murders in the Building Season 5 Review
‘Only Murders in the Building’ is Starting to Show its Age in Season 5. The new season of the comedy murder mystery series remains resolutely entertaining, but some of the schtick is starting to feel a little careworn. For the last few years, ‘Only Murders in the Building’ has been a reliable provider of murder mystery mixed with the vaudeville comedy of Steve Martin and Martin Short, plus a side of eye-rolling millennial reactions from Selena Gomez.
The combination has worked extremely well, providing confounding cases and lots of laughs. The question is, however, does the fifth season do enough to differentiate itself from what has gone before, or should we be happy that we’re getting more of the same if it’s still entertaining?
