Yikes!! 'Asunder' packs a serious punch --- I found myself clutching my chest, in great fear for the characters pursued by Chance (Blair Underwood, who proved long ago, in 'Just Cause', how scary he can be!), for the bulk of the film. Adrian Lyne's 'Fatal Attraction' no longer holds the trophy for this scorned-lover-comes-back-for-revenge-genre. See it --- you won't be disappointed.
