Not succeeding as a World War II drama, spy thriller or love story, “Allied” is what you will find in the dictionary if you look up “insipid.” It’s hard to squander the star power of Brad Pitt and Marion Cotillard together, especially if they’re handsomely costumed and smooching a lot, but somehow it has been done. If it was a student-thesis feature in film school, it would barely earn a passing grade. It is vanilla banality run amok.
