Strange Bedfellows was one of those episodes that I wasn't sure what to make of at first. After further viewings, I think there are both good and bad things and that it is neither among the best or worst of the series. That said, if I were to rank the Columbo episodes Strange Bedfellows for me would be somewhere around the bottom, not because it's terrible but because there have been better episodes and so many good, often amazing, ones.
What were the good things? Well as is the case with all the Columbos, it is filmed and directed beautifully, and has a good score. I did admire that it attempted to stick to formula after some episodes that tried to be different but failed due to bad execution, it was mostly interesting and had some good scenes, with Columbo's triple bluff being the highlight of the episode. Of the support cast, Bruce Kirby was fun and Shani Wallis was a nice find but my favourite was Rod Steiger, not his best role but he is very good here.
Peter Falk does a fine job with what he had with the iconic character of Columbo. He has a lot of charisma and has some inspired line delivery. I wasn't taken with how Columbo was written in this episode though, Falk does make an effort to make him true to how he usually is but the material works against him. Columbo does seem out of character(note I said seem before somebody objects), and is not as likable as he often is. It is not as bad as him sending himself up in Last Salute to the Commodore or being almost completely sidelined in No Time to Die, but it didn't work for me.
My main problems though were the script and three performances that didn't work for me. There have been much cleverer, more arch, funnier and more tense writing before in Columbo, here the cat-and-mouse scenes between Falk and Wendt that are often highlights of Columbo seemed bland and lacking in tension and the script seemed very pedestrian in places. George Wendt I agree is too boorish and too unsubtle in his role, but he is at least better than the dull Jeff Yagher and the irritating Karen Mayo-Chandler.
All in all, a strange episode that at the end of the day I was very mixed on. 6/10 Bethany Cox
