Changing perceptions

Posters and images of a movie look so different before and after watching the movie. Your perception of what a particular expression meant to convey could become completely different from the start to the end of the movie.

Two examples come to my mind, both my feature in my top movie list.
---- Omen:------ If you look at the kid without seeing the movie or knowing what character the kid plays, most people would say the kid is very cute. The kid had a look which most women would have said "ohh.. So cute etc"
Having seen the movie, I cannot get past the kids character (Anti-God) and the same poster which I thought was cute before the movie freaks me out. Every expression in that poster now conveys evil.
Nothing has changed in the poster, kids, color background or anything. It is just my perception has changed.
----Shawshank Redemption:--- The scene in the movie where all Andy Dufrense and all the convicts are brought to the shawshank prison. When you first watch the movie you see the look in his eye as someone who is completely defeated and weak. But after seeing the complete movie and understanding about his character, when you go and watch the same scene again. You do not see a weak, defeated person but the same expression now convey a super will.
I have watched this movie over and over again several times. Each time I seem to notice something different (I have watched this movie so many times that it has been "banned" in my house :) ) . Watch this movie if you haven't.
Again exactly the same scene but you just see it differently
