From "Andrea Riseborough doesn’t deserve Oscar nod — Danielle Deadwyler was robbed/The British actress’s performance in To Leslie is a one-note cliché, says the Times film critic Kevin Maher" (London Times).
Riseborough, a white actress, was touted by white actresses, and got a surprise nomination, and Deadwyler, a black actress, was, surprisingly, not nominated. Even though Oscar nominations are campaigned for, this particular campaign is deemed suspect because it worked so well and because it happened to undercut Hollywood's efforts to seem racially inclusive.
