Rotten Bananas or Overly Ripe?

I am one of those that does not keep bananas that turn brown and if I do, I freeze them, only to never unfreeze them! But tonight, I pulled some brown bananas out of the refrigerator to make banana muffins and I could not decide- is there a major difference between rotten and overly ripe.

I know you want the overly ripe, but is there a time when it gets to be too much? I went ahead and made the muffins, but I cannot tell still if thy are actually good. it could be that the recipe was bad since I "adapted" it- I never make a recipe the way it says too.

I guess my husband will be the judge! And we may just throw them out!
