Never started it. I was thinking I was going to start it when it had an ending. Now I see no reason to ever bother starting it. Good thing I'm patient. I did the same thing with GoT. Dodged two bullets.
Its not worth it to me to get invested into a series that I know will eventually disappoint me. I have limited time to watch TV and I want to make it count. As good as I know the first couple seasons are, what's the point of I know it's all leading off edge of a cliff and nothing will actually matter?
Breaking bad doesn't disappoint of you haven't watched that! It's the show that made me get over the "new shows always suck" grandpa mentality so then I tried game of thrones and it was very enjoyable until the end, but even with the end the ride was still worth it.
