Knowing what level of recommendation to give

The Michelin star rating is clear:

One star for a very good restaurant. Two for a restaurant worth a detour when travelling. Three stars when the food is so good, it is worth a trip there.

Our recommendations to each other are not always that clear.

Some movies may be worth a life-detour: The kind of movie that has to be seen. Others are only really good if you are going to watch a movie anyway.

When people ask for recommendations it is helpful to know what start of recommendation they want.
