I seem to differ from many of my fellow "monster movie" fans because I find this film the best of the series and in many ways one of the better horror flicks from this era. The reason for this preference on my part is because the human characters are rich, the actors do an excellent job, especially Jeff Morrow, and the focus is on the relationships between the characters against the backdrop of the adventure of again capturing the creature and then dealing with what to do with him when they get him. These relationships are as complex as my last sentence. The film opens with establishing a very strained relationship between Dr. Barton and his wife Marsha by inference of their nonverbal behavior. We soon find that Dr. Barton is not simply a very suspicious man afraid of being turned into a cock old by his young sexy wife. He is exploding with paranoia and she is repelled by him. This sets the underplay of all the remaining events in the film. Dr. Barton is a narcissistic, arrogant man besides paranoid. And, these are his more charming features. Jeff Morrow, who usually played a good natured hero, gets to show his muscles an actor by making himself totally repulsive in this role. Rex Reason is very good in his role and does so by using his good looks, great voice and easy charm to underplay his part. Thus, he makes himself a pleasant contrast to the splenetic Dr. Barton. Leigh Snowden as Dr. Barton's wife Marsha is, well, very good and also underplays her sexuality so well that it becomes intense. For those who look at a "monster movie" and think the plot of the movie is the monster, which in a good monster film would never take place, this film is not for that person. For those who like a little gem of good acting and interesting characters- enjoy this film.
