No I have plenty of positive things to say on a wide variety of topics.
The Q400 performs well for a turboprop, but is lightly (and poorly) built. I know this because I have had first-hand experience of them. I doubt you have even seen one.
We had a lot of problems with them. I lost count of the number of times I had to saddle up the trusty 146 and rescue a planeload of stranded pax from a dead Q400.
Maybe when you get beyond the right seat of your little turboprop, you will understand a little more about the industry.
