Mark Jenkins starts his review of 'Charlie St. Cloud' thus:
As the title character, Disney pinup Zac Efron doesn't have enough substance to be a cloud; he's more like a barely perceptible Pacific Northwest drizzle, although he'll presumably become more noticeable to the film's target audience each time he takes off his shirt.
I saw a trailer for 'Charlie St. Cloud' which included an exchange between two characters outdoors. Every shot of Character A was lit by the sun, while in every shot of Character B (a few feet away) the sun was obscured by clouds. The effect, cutting quickly back and forth during a conversation, was jarring -- embarrassing to watch. I completely wrote the movie off based on just that scene.
The script (by all accounts) is weak, the direction was of the 'furniture-mover' variety, and editing barely qualifies as utilitarian. And, why feature a technically flawed scene in the trailer?
I don't know why they even bothered if nobody cared about the material.
