1. Nobody perfect
2. storyline too cliche when everyone's too strong
3. revenge cannot be used as an excuse if everyone are strong
4. love and hate do exist in this world
5. we create our "feeling" for the characters, not otherwise
6. use common sense
7. the dead ones stays dead unless stated
8. sadness happens from time to time
9. learn to accept any weakness and disadvantages
10. never assume anything final until it ends and it really ends that way.
Enough said. Just my 2 cents.
