I'm probably in the minority, but I rather like the bonus episodes Universal includes. I don't know what motivated it, but as long as studio extras don't interfere with what I buy their products for, then it doesn't really matter to me.
The Mrs.Columbo eps are great for mealtime viewing, and I noticed that they are being released in chronological order. "Caviar With Everything" is ep #3 in the line-up, and stars Trisha Noble, better known to most of us as Marcy from "PLayback".
It should be interesting to see what they do with season 6 -- if they don't end up combining it with 7.
