Roseanne makes movie fail....
The not-so-great script doesn't help, but it would be SO much more interesting if the lead were cast with someone who could actually ACT.
Roseanne Barr does nothing in this part that she didn't do on her TV show...playing a character that was tailored around her own personality.
The character of Ruth from the book is almost majestic in her wrath. And smart and capable. They really needed something more than a 1-note performer in the part (I don't even know that Barr qualifies as an "actress", really!)
