Every time I watch this series
I hate Marie even more than I did the last time I watched it...
GOD SHES ANNOYING
About 95% of the time, yeah. She got a lot of points from me, though, with the "talking pillow", and she was the one to step up and say, "Walt's the one who should be the focus here; we should respect his wishes." Elsewhere, we do see she cares about her family, and I think in some ways she's a good counterbalance for Hank.
She can be really obnoxious, though, especially with her ducking the responsibility for her kleptomania.
