You don't have to have anything against Steven Spielberg to have the problem you mention when it comes to MURDER BY THE BOOK. Speaking of "wincing," that's what I do when I look at the Season One box set and notice that he's the only director who's mentioned by name on it. You'd think they'd at least have balanced things by doing that with Peter Falk himself when it comes to BLUEPRINT FOR MURDER.
Murder Under Glass was definitely one of my favorite. Louis Jourdan was a fantastic,stylish villain, and I love when the two of them admitted they did not care for one another. I think that is the only time Columbo lets you know exactly how he feels about a murderer.
