Your rating is quite fair for this movie. I saw the highlight and downloaded the movie and I must say it's a worthy watch.
Change is constant even the worst sinner can attain repentance. And forgiveness is a blessing. I felt for her friend when the pastor proposed to Adele. She didn't feel envious about Adele getting married before her after ruining her own relationship by sleeping with her fiance and all her excesses. She's truly a good friend.
The pastor rep his role well. I actually like the fact that he didn't give up on her and kept proposing.

Movie suggestion: have you seen the movie casa de novia? You might enjoy the plot twist. It's highly fictional but portrays some unplanned consequences of our actions...
