Maybe it was a good film in the 70s, but now...
Man, it started off nice and mysterious and gets you into it, but then it falls apart. Fast. For some reason, Hollywood continues to show us kidnap victims who end up falling in love with their captors. To make matters worse in this film, Faye had a loving boyfriend awaiting her on vacation, and Robert's girlfriend had just been murdered a few hours ago...perfect time for a kidnapper and his victim to have consensual, unfaithful sex.
Then there's the evil murderer Max Von Sydow. He is such an evil character that at the end, he gives Robert a ride to the depot and hands him a gun. Wow, if only all movie villains were so nice at the end. So I guess that means the true villain was the CIA guy Atwood who had hired Max. Nothing like the climax of a movie where the bad guy (who we barely saw the entire movie) gets killed (not by our hero, but by an intermediary quasi-bad guy). Way to go Robert! Way to get revenge for your girlfriend's murder by...well, by doing nothing. Wow. Awful awful plot twists ruined an other compelling beginning.
Oh, and if you're a CIA director and you sense there is an intruder in your home, just go downstaris, unarmed, in a bath robe. Great spy he musta been.
