Good series, based on Celeste Ng's novel of the same name (which I have not read). So it's a miniseries with a clear beginning and ending, not a continuing, ongoing drama show.
Dares to go some places lots of shows won't. Character driven drama show. Best you don't know anything about it when watching it (I didn't either), so what's it about without spoilers?
Drifting artist and single mom Mia Warren (Kerry Washington) rents a house from well to do journalist Elena Richardson (Reese Witherspoon), who lives a perfect family life with her lawyer husband (Joshua Jackson) and four children in Shaker Heights, Ohio.
Everything could almost be just about perfect for everyone.... but it isn't... and, alas... as everyone should know but always easily forgets... little lies and secrets start little fires that may well grow into larger fires...
