Good movie, time to share my thoughts.........spoi lers
I get the feeling Alice is used primarily as a classic red herring. She's weird, she's spooky and she has "crazy eyes" too. The audience never forgets her as a potential suspect.
Now I know Mrs. Tredoni killed Karen. Her motives seem to be based on children getting punished for their parents' sins which is why she feels HER child died. What these sins are would be anyone's guess. The premarital sex, or I always found the parents' divorce was another indication. This movie is set in 1961, divorce was rare outside the church let alone inside the church. Plus doesn't Mrs. Tredoni imply that Catherine shouldn't get Communion either since she isn't pure?
The one thing that gets me is this. Why in the world does Mrs. Tredoni attack the aunt? What was her motive there? I can see killing Karen. I can see killing Karen's dad since he was closing in on the killer (or trying to). I can see killing the landlord since he interupted on her plans. But the aunt I don't understand. Makes me wonder if it were Alice, but I guess we are always just to wonder about it.
Also one weird thing struck me. At the end the cops have the church surrounded. I know the last thing they want to do is come into a holy, solemn place and make an arrest of a person who wouldn't go quietly. But why did they do that. I know Father Tom tells them "not in my church you won't" but you'd think the cops would override him and figure they can nab Mrs Tredoni while they can.
Lastly, at the end I too got the feeling that it was implied Alice might just take up where Mrs. Tredoni left off. But was there an alternate message that was being displayed? Were we to believe Alice was involved more than we think?
