Last time we saw the least good. This time, let's move up to the C list of Columbo. Those episodes which don't work, for a variety of reasons, but have enough in them to be enjoyable watches if they are on TV. Some might be quite bad, but amusing. Some might fail on a basic plot principle. Some might just miscast badly a crucial role.
Sorry, George Wendt, I know all of those refer to your episode but I'm not picking on you. Honest.
Some even might have gone in Part 1 if not for one thing which raises them from the bottom rank.
Without further waffle, the flawed diamonds in the rough of Columbo!
