I hit my breaking point in season 8. I was able to stomach the rest as each season had its high and low points. I really started hating Deb at some point and that affected some post Lithgow season watching. If season 4 was bad I probably would have stopped watching then. Season 3 was pretty damn terrible, and the resolution to 2 was awful in its own right.
Thanks for all your posts. Now I'm re-watching S01 (then, eventually, the 2nd...yep, like I said, loved them :D) with my girlfriend, who also fell in love with the show, then see who this John Lithgow guy is

This show was created by cowards who wouldn't know tension if it bit them on the face. I gave up during season 5. The end of 4 was definitely the high point. I almost quit after season 1 when Deb didn't die. She was nails on the chalkboard every time she was on screen.
