Serious question, do you think all episodes of this show are great?
I think you're overrating it a tad.

I thought it was pretty average again. As Bileduct said that Francine scene was ridiculous and pretty much repeated later on in the episode at the warehouse, though it that situation it was slightly more believable. The Doctor being an abusive husband seems like lazy writers finding an excuse for Rick to f**k his wife. Carol acting like a complete arsehole to everyone seems stupid, even when she killed the people at the prison she thought she was doing it in the interest of everyone. Preacher man f**king things up also seems stupid considering the fact they kept him alive when he's pointless proves they have at least somewhat good intentions, though I suppose you can't expect coherent thought from someone invoking Satan.
