You'll hear both good things and bad things about all restaurants, it seems. While some might suggest to ignore the reviews, that doesn't leave you much to go on in terms of making the best choices for your family, and reviews are actually a very valuable means of making trip planning decisions. The key is to know how to read a review and interpret its message with regard to your own circumstances.
Here's an extreme example: For my recent trip, we didn't visit all my favorite restaurants, because my favorites are based on our typical WDW trip: My wife and I, either alone, or perhaps with some adult friends. This time, we brought my younger brother's family along, folks who have substantially different tastes from my wife and I, so my favorites wouldn't necessarily be the best for us, this time.
Besides the ages of the diners, personal preference plays a very strong role, not just with regard to cuisine but with regard to other aspects of the dining experience. I tend to discount reviews from folks who are "meat and potatoes" people, or who are fast food people. I tend to regard very highly reviews from people who like fine dining, and even reviews from wine afficiantos, even though I don't drink wine, because I have found, through experience, that those folks preferences with respect to dining most closely align with mine.
So the trick, for you, is to read the reviews, and then ask yourself, for each one, to the extent you can determine it from the writers' manner, demeanor and written descriptions of themselves, whether this is a person "just like you" enough for their review to be relevant to you. Good luck!
FWIW, I have had many great experiences at Narcoossee, and find the place to an excellent choice for a fine, casual dinner. The cuisine is sufficiently run-of-the-mill that folks who avoid exotic cuisines will be fine there. Of course, seafood lovers will be happier than meat-eaters.
