This film is a guilty pleasure from the go, go 80's, when money was a balm for all things, and everything over the top was fun.
Teresa Russell is very good as the elusive "Black Widow", a beautiful and mysterious chameleon who marries wealthy businessmen, somehow rids herself of them, and financially profits in the process. She goes from NYC society matron, to Texas redhead, to Seattle museum doyenne, to Hawaiian princess. She looks the role, and Debra Winger is very good as the frumpy FBI detective who must catch her.
There are also some memorable cameo roles here, Lois Smith as a former sister-in-law, and Diane Ladd as the suspicious relative in Texas who is bought off with a substantial six-figure gift.
The sets are believable, and the final set in Hawaii is also balmy and mysterious. Sami Frey portrays the final husband, and there is a twist at the end. 9/10. Recommended.
