Fandom: Gilmore Girls

I am staring at my television, completely confused by Gilmore Girls, specifically "A House is not a Home," the season five finale. I do not understand what exactly happened over these past few episodes, but especially this one. I do not buy most of the character choices (though really pleasantly surprised by a couple secondary character things).

I should probably just stop now, yes? I mean, I'll watch the next two seasons because I haven't seen them, but wow. Did they change all the writers and producers and directors, etc., involved with the show? This is kinda like that time when Anita Blake went from having somewhat fun mysteries to solve to only have sex with approximately a page of plot. It feels like a completely different series.

Weird.
