This episode is really entertaining. The cowboy theme and nods to wellknown Western movie tropes is well observed. It's also a study on the blurring between fantasy and reality and what can go wrong when an interest becomes an obsession. The denouement stand off at the Midsomer Corral is seen through the eyes of the villain to great effect - he has detached from reality and it's chilling. And you get to see Barnaby as Wyatt Earp! What's not to love!
