While this kind of tale is a fantasy for the movies, with an emphasis on realism in style and deliberately paced story, "Before We Go" suggests that it really can happen, even just for a fleeting moment.

Slight and familiar but sweet enough for Saturday night, Before We Go is the umpteenth re-up of Brief Encounter, not that there's anything wrong with that.

Very little here is special, despite the individual charms of Evans and co-star Alice Eve.

For the new independent film Before We Go, it's Chris Evans's turn to be be a first-timer. The promise is there, but he has a long way to go.
