Agree with @supersim2000 that this is a zero-star as stated. That would actually be a helpful level for those just starting, like the zero level in rock climbing.

I don't understand the negative ratings.
It's a very easy puzzle, as stated in the description, and the thermometer, kropkis and diagonals complement each other.
