Spike Lee needs to relax ... so says "Chappelle's Show" star Donnell Rawlings, who tells TMZ, the n-word-filled "Django Unchained" is a fun movie with a happy ending ... and THAT'S IT.
Rawlings was out in L.A. last night when he came to Quentin Tarantino's defense -- blasting Spike Lee for his criticism of Quentin's usage of the n-word in the film (110 times to be exact) ... which Spike called disrespectful to his ancestors.
Donnell said, "Spike Lee, I know you been talking a lot of sh*t. You don't like nobody's movies. You don't like Tyler Perry movies. You don't like Quentin movies. I don't even think you like YOUR movies."
By the way, Donnell's favorite part of the movie? "NO SLAVE VOICE!" You gotta see his explanation ... pretty damn funny.
