Tom Cruise gives his standard Cruise smirk and nothing more, so his character has no real development. Dakota Fanning, playing Cruise's daughter, spends the entire film screaming, in a hugely irritating performance. The plot, which is sometimes borderline illogical, sets up several possibilities that are later simply dropped. The feel-good ending is implausible.
The original version is one of the greatest science-fiction films of the 1950s, and one of only a handful of films featuring a full-scale alien invasion. (Others include Earth Vs The Flying Saucers, Independence Day, and the parodic Mars Attacks.) It is also, however, an overtly Christian film, with a quasi-Biblical narration.
Surprisingly, this religious aspect has been retained in Spielberg's remake. Spielberg's film, a blockbuster 'event movie', was released around the world, yet he still included references to "God's creatures" in the narration, turning American cultural imperialism into proselytism.
