Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE reviewer ( rid number, name text )
TABLE: CREATE TABLE movie ( mid number, title text, year number, director text )
TABLE: CREATE TABLE rating ( rid number, mid number, stars number, ratingdate time )

### Question ###
What are the names of all reviewers that have rated 3 or more movies?

### Accurate SQL ###

SELECT T2.name FROM rating AS T1 JOIN reviewer AS T2 ON T1.rid = T2.rid GROUP BY T1.rid HAVING COUNT(*) >= 3
