I'd heard Lost was a work in progress didn't know about Breaking Bad. I've written end towards the middle before but almost every time I've tried without a ending that's where I've finished too. Often I can't even make a start without an end - even a poor end - in mind. middles are no problem, everything mid story is soft and malleable and just waiting to be given form.
