Only murders asks a lot from the audience because none of the plot is plausible and so to enjoy it you need to be willing to accept the invitation to go along for the zany ride. Often it is explicitly meta when it breaks the fourth wall and subverts genre expectations, but sometimes it seems to slip back into a conventional show so is a little confused here. But if you do accept the invitation then you are rewarded for the investment with some really enjoyable chemistry between the 3 mains, some one liners and gags which make you laugh out loud, and a nice reminder of the joy of not taking things to seriously and a murder mystery entertainment for its own sake. Short and sweet 30 min episode are welcome for such a show and make it easy to watch them either here and there or all in one go without much effort.
