Everyone is entitled to express their option, and that particular host especially so...
To be honest, I've generally heard very few negative comments about Boatwright's, and we've always been happy with the food when we've eaten there. Others in this thread have commented that it is a bit of an underrated hidden gem at Disney World. However everyone's tastes and opinions vary, and everywhere can have an off day, and there are lots of other choices at WDW if you feel nervous about eating there based on that one particular podcast comment.
