I got to the third season and stopped watching, but I don't know why, I just stopped. I don't remember much.
I hope you watch it the entire way through, i watched the ending of the last episode (although i wont say what happens) and its interesting.
What I will say is that the alternate ending that isn't considered canon (even though it was officially made) is better, since it references Malcolm in the Middle (Breaking Bad is a dream and Hal wakes up)
Also, forget you stuffty.
