Don't forget Howard the duck...
George let me down the most. I had little invested in M. Night, so I can't say he let me down, as such. I'll never forgive Lucas for the travesty of the prequels though.
Don't even get me started I Spielberg and that crystal skull ****.
I dunno. I never see Night's twists coming because I didn't pay attention to the movie in the first place, so I'm like wtf when they occur.
