The "religion crap" was fine. If RDM would've had a "plan" and stuck to it, it would have made more sense. This was discussed in another thread not too long ago that the OP might have just found and took part in.
This was my issue with the series, especially after a season and a half. If you're going to tell me "They have a plan" every single week, then it better be a damn good plan. It ended up being a really sucky plan.
