It would depend on your definition of "amazing." A definition from Dictionary.com is: causing great surprise or sudden wonder. If we follow this definition, you would say that a rescue for slugs might be an amazing rescue - learning that there is a rescue for slugs would probably cause you great surprise. A definition from the Urban Dictionary, however, is this: Something that is so wonderful, it is hard to find the Words to match. This could be any rescue, depending on what you like. For me, Mickaboo Companion Bird Rescue is an amazing rescue, because I think their mission is so wonderful. But if someone doesn't care about parrots, they probably wouldn't think Mickaboo is an amazing rescue. In short: it depends.
