grouping joining and cleaning up challenge 3rd task

Hey there.

In the above mentioned challenge I'm supposed to do the following:

Like before, select the average "score" as "average", setting to 0 if null, by grouping the "movie_id" from the "reviews" table. Also, do an outer join on the "movies" table with its "id" column and display the movie "title" before the "average". Finally, include averages under 2.

I think I got most of it right but I'm not 100 percent on the outer join. already tried left and right, nothing worked. Maybe someone here can help me Thanks in advance

Hi Daniel Schwemmlein, can you copy and paste here the query you tried so we can help debug it?

Can you post the code you've gotten to pass? Also, did you take a look back through the video? Usually the code challenges are very similar to the example the instructor goes through in the video.
