This weird spinoff is in fact three shows in one. The first season, where she's firmly Mrs. Columbo, isn't bad, but would be better without the Columbo tie-in. The first five episodes of the second season are an absolutely dire cop show where Kate is in constant peril, but the last three turn into a surprisingly good and sustainable take on the Columbo formula - just in time to get cancelled. If they'd just done a Columbo-inspired show with a female lead, this could be remembered fondly today.
