When I attended Catholic high school back in the 90's, we were shown the awful images of abortion, and it did frighten and sadden me, so the movie didn't shock me.
Maybe that's the problem, that it does shock some folks? Clearly we need better education in schools. I for one, never managed to get pregnant in my 39 years.
With that said, it still hasn't swayed my opinion that abortion should still be available. I felt the movie was a little extreme. I believe the goal is to educate people, especially our teens, and to make it rare, but not to eradicate it. Bringing a human being into this world is no small responsibility, and each woman's situation is different. Nobody should be forced to carry to term and have a baby against their will.
Don't know enough about Planned Parenthood in actuality, though I found the idea that they'd want to increase abortions disturbing. So that part surprised me.
All in all, it was an interesting movie, but it only strengthed my personal beliefs.
