This is probably one of the best movies to use when demonstrating a surround sound system which has a powerful special effects element to it. The sound of the river as it thunders down the gorge is awesome.
As for the movie itself, Meryl Streep is superb, Kevin Bacon is suitably menacing and John C Reilly works well as a bit of a dupe. Benjamin Bratt makes an appearance as a park ranger.
the plot is a bit formulaic as in husband and wife struggling to work things out. Husband misses a holiday. Wife heads out anyway, gets caught up with some bad guys. Husband saves the day. Most of the good guys get tpo live happily ever after.
