Absolutely ageed. I hate that all TV shows seem to think that it's impossible to write a happy couple, so at all costs, they must dredge up some kind of drama, no matter how supremely unrealistic, to force them to be apart for a while.
In what I'm assuming is going to be the last season of the show would it have killed them to throw the fans a bone, you know? And I'm sure that somewhere, given that Luke and Lorelai are both, you know, interesting characters they could have come up with some kind of plotline for them that didn't involve the tired, breakup, will the ever get back together, omg! plot. All they've really done with it is to make kind of not really care anymore if L&L reunite or not - they are kind of both so distasteful right now that it would almost not bother me if they didn't.
