Young Dakota Fanning's performance was great, but when that performance calls for her to yell shrilly and otherwise be ultra-difficult while aliens are busy flattening the planet around her, we can't help but roll our eyes. To be fair, her older brother Robbie is no prince, either, as a perpetrator of the tired "butting egos and heads with Dad" trope. The fact that neither of these kids gets incinerated by the aliens (call it a lesson to little ones that they should act right, if you need to justify it) is director Steven Spielberg's greatest failing.
