I agree with Bob 100%.
Our last trip, Biergarten, Play-N-Dine breakfast and Chef Mickey's were getting hammered in the reviews... to the point I almost switched my ADR's. As it turns out we loved all three and will be doing all of them in June.
We never did 1900 Park Fare but are going to try it this time too.
My personal view on these reviews is that many folks have expectations that are just too high. Granted, when you are dropping almost $30/meal you expect something, but it is a buffet and some of that cost is for the whole character experience.
For example, I can't count how many times I see on these boards something like..."Blah, it was just a burger" if someone was eating at a counter service place. Well... what does one expect? Don't get the burger if you didn't want it!
At the buffets like Chef Mickey's or 1900 Park Fare, there are usuall so many things from which to choose that everyone finds something. I usually reserve my opinions for things like cleanliness, was the service good, how was character interaction, etc. Remember it is a buffet and it is tough to keep things fresh, but they generally do a good job.
If in doubt, do the breakfasts because they are always good, although that won't help us at 1900 Park Fare if you want to meet Cinderella like my daughter does.
By the way, the Epcot princess breakfast was AWESOME. That is one we will never miss again, even when our daughter is all grown up!
