Just look at the ingredients.

The Chicken by-product is the problem. that and the corn gluten. Those being the first two ingredients tell me that this food is mostly processed junk. Also most animals do not need brewers rice or soy.
Furthermore even though the company does sell better products I have ethical issues with buying food from a company that will sell crap as well as quality. If they know what good food looks like all their products should be good food. That's just me though.
