I really don't get why this show has such a high rating. Granted, I've so far only watched the first episode, so maybe the show just takes off after episode 1, but even the first episode has a 8.3 IMDb score which to me is a complete mystery.
The main character (the OA) acts like she is walking a knifes edge between bordering retarded and mysteriously gifted - sometimes she's secretive to the extremely annoying, and other times she can just persuade people to do things that are so extremely unlikely. No matter what she just annoys the hell out of me, and this may make me biased.
The side characters are okay. The OA's parents are pretty 2 dimensional, and so are most of the side characters (again, judging from first episode only).
The plot is confusing, and the first episode uses almost 1 hour developing what I hope is the monster of all plots 'cause else this is going to one boring train ride.
I'm not going to watch any more of this show. The main character alone is enough reason for me to quit now. She is annoying me so much. Maybe I'm wrong, so if the next episodes rock your socks off, then let me know!
