I wouldn't cancel anything because of reviews - you don't know the reviewer or what their expectations are, or what may have by chance happened to their food that day.
For instance, many complain that Ohana has gone down in quality over the years. I'm sure it has, but I never went in the past, so I'm coming in with a fresh perspective and don't have that lingering thought in the back of my mind. So, all things/foods being the same, I may like it more than the 20-year vet who remembers how much better it used to be.
Just something to think about...
