Til Death Do Us Part

I'm halfway into the movie and it's irritating me because I can't believe that Vanessa is just helping to bury these people that Terrence is killing. I'm still not sure exactly why Terrence is doing this except for that Rachel was supposed to marry him and she called it off and left him at the altar. Since Rachel's ex happens to be on the island and killing people/having people killed, I would think that Vanessa would alert her friend. Kind of a stupid movie actually but I watched the rest of it because I was curious as to how it wasgoing to end. Another thing I didn't like about the movie was Vanessa constantly using the F-word. Wasn't necessary.
