War Horse is a Steven Spielberg film, all right. Sound and fury, emotion on its sleeve, very handsome photography, first-rate actors conveying sensitivity and compassion. But beware of any shot of any young actress with a tear running down her cheek. Beware of dolly-in shots of handsome young farm lads. Beware of title cards that say “touched by kindness” and “hope survives.” Beware of French horny orchestral music that tries to melt you down.
