Stephen Kendall’s review published on Letterboxd:
Mostly slow-moving and too talky, with weird mid-Atlantic accents from a time when American audiences apparently expected every main character to sound like they came through the American Ivy League no matter where in the world they were from. But Niall MacGinnis's character Dr. Julian Karswell almost makes the movie worth it. His character is the kind of civilized villain who offers you the best hospitality possible even while openly plotting your doom. I know that kind of bad guy is a movie cliche, but I just can't get enough of them. The rest of the movie is very forgettable.
