Questions about the movie in general!

1. Does Ig have his name cleared?
2. What happens to Veronica the waitress after Ig gets revenge on her?
3. How come Ig's parents hate him and do they even miss him at all after his death?
4. I can't figure out the ending. After Ig kills Lee and turns to stone, it is implied that he and Merrin are reunited in the afterlife, but all we see is the opening scene of the movie. Is that the afterlife? If so, why would they say that they will love each other for the rest of their lives when they are dead?

God, this movie sucks!!!! >:(
