I loved Anna. I think she was awesome in the pathetic tradgedy that was her life. What can I say? I have a soft spot for people like that.
It's hard to say if this movie will do her memory justice or not. I'd imagine not, but you never know. At least they didn't portray her as a gold-digger just marrying that guy for his money.
I like the ending after she dies where she gets into the car with her son in the passenger seat and laughs. I think she is finally, truly, happy.
