No, as I've already said it's been globally recognised as a masterpiece and Ejiofor praised for an outstanding performance, I'm just going wiht the general concensus:

Many critics also praise Ejiofor's performance, with THR's McCarthy writing that the actor "is terrific in a demanding character who’s put through the wringer physically, mentally and emotionally.
Travers writes: "As Solomon, Ejiofor gives an electrifying, engulfing performance that will be talked about for years. The educated Solomon is forbidden to protest his situation or even articulate it. Not without being beaten or worse. But Ejiofor's eyes, deep pools of confusion, pain and barely repressed rage, tell us all we need to know. Want proof that acting can be an art form? Here it is."
New York Magazine's David Edelstein adds: "Ejiofor has been overdue for stardom since Dirty Pretty Things, and he’ll get it now. He’s the kind of great actor who can work in pantomime, conveying terror and anguish with the angle of his shoulders and the level of his head. At times he wears his disgust too visibly for a man who has supposedly learned to keep his head down, but the struggle to remain inside himself is vivid."
Dargis claims, "Ejiofor’s restrained, open, translucent performance works as a ballast, something to cling onto, especially during the frenzies of violence."
Yet the likes of you, who also hasn't seen it make the inexplicable claim that we don't need films of such nature to be made.
Thankfully, the BFI, Hollywood, actors, directors and producers don't listen to the likes of you.
