On paper this is a regular, improbable, coincidence-riddled stock Hollywood film isn't it? Boy-meets-girl, both die in plane crash, very surprised ex-partners discover each other, etc. We get the obligatory US government angle plus a corrupt cop investigation, chase and shooting thrown in too. Now watch the film and read Ebert's review. Janet Maslin, another critic, wrote 'laconic Ford is wrenchingly effective throughout'. That works for me. How accurately the word 'wrenching' describes it all.
Harrison Ford is disturbingly, self-revealingly good. Kristin Scott-Thomas is always good. Their cold, understated earlier conversations are first class I think and the opening situation (and scenes) will haunt you for the rest of the film, maybe longer.
