I recently consumed a Kelloggs product for the first time in years, just because it was on special. It was - not great.
Why do Kelloggs products seem to so uniformly be so dull and overpriced? I wouldn't say "bad quality" as such; just really uninteresting and expensive for what they are. I've felt this about them for perhaps 40 now, and nothing changes. I presume this is not a assessment too widely shared, given the survival of the company, but I feel very certain of my opinion on this anyway.
PS: I've eaten a lot of breakfast cereal over those 40 years. I love a good breakfast cereal. Uncle Toby's or some Sanitarium have had much better cereals, although they didn't up their game when I was a child, and it probably was mostly Kelloggs I ate back then. Now, I'm into the cheaper toasted muesli style products (Heritage Mill, sold in Coles and made in Australia, goes ridiculously cheap on about a 4 or 5 week cycle and has been my favourite for a year or two. Just so you know.)
