ABC's "Scandal" is one of those shows, like "24," that are compulsively and obsessively watchable despite the utter ridiculousness of the plotlines. To be successful, the action on the screen has to come so fast that the viewer doesn't have time to register skepticism, because something else demands immediate attention.
Of course, "Scandal" drew much attention early on for being the first TV show in a long, long, long time to star an African-American actress. Kerry Washington certainly deserves accolades for her portrayal of D.C. fixer Olivia Pope, who exudes competence and control no matter how absurd or seemingly hopeless the latest political crisis to deal with (except when she's swooning over the President, and he over her, which is the weakest part of the show's DNA).
The show can even be given a pass on the diversity front for not having any Asian characters; producer/creator Shonda Rhimes cast Sandra Oh as one of the main characters of "Grey's Anatomy," so it appears that the absence of Asians on "Scandal" is not some sort of blind spot.
However, where "Scandal" falls completely apart on the diversity front appears to be in the ideological diversity of its writers. If there's anyone on the writing staff who isn't at least a mainstream liberal, if not more progressive, you wouldn't know it from the show.
