To Have Been 'Inspired by Cooley High'
This show was awfully different, the only similar characters are Raj, Dee, Mama,and Dwayne somewhat, and maybe the setting of the soda shop but otherwise Whats Happening is way different and quite a bit goofier than Cooley High which was more of a dramedy than a straight forward comedy film.
Also, Cooley High strictly takes place in the early 1960s while Whats Happening clearly was the then modern day 1970s.
