Each shot is as unpredictable, on arrival, as possible. Well, perhaps there are problems. The director, unaware, doesn't share the screenwriter's style, except in his failure to build a complete movie out of a series of impressive moments. A director's other job, besides getting the scenes on film, is making the scenes happen, especially in helping the actors to create their roles. The supporting actors in The Beach all seem good and likable, and not very special this time.
None seems to have much to do.
This, too, seems like a failure of directing. Even DiCaprio's acting at the end, which in a different film might seem bravura, comes off as grotesque because there's no context of meaning to support it. Some viewers may be too quick to notice the unintentional humor in it. Readers of Alex Garland's novel may feel positively betrayed. Other viewers may enjoy it.
