Cookie-cutter isn't a bad thing. If it solves a real problem or addresses a real need, it will be successful.
I mean Facebook started out as a cookie cutter app. Heck, it was a basic CRUD app. Look at where it is today.
Outside of such unicorns there are also many examples of reasonably successful products that can be categorized as cookie-cutter. Basecamp. Trello. Snapchat. These apps don't do anything groundbreaking or operate on the bleeding edge of technology. But they are well-known and profitable.
