One thing I like about Bates Motel is how it plays with the movie Psycho and makes you interpret things differently.

Norma’s a bit erratic and way too possessive, sure, but she was never anything close to the monster Norman warped her into in his mind after she died. 

I mean, she could have dealt with his problems better, but really, he was probably always going to have some major issues regardless of what she did.

I kind of think a big theme of the show is: There’s only so much you can blame Norma for.
