What was once startling and shocking is now more humorous than anything else. This early Cronenberg film delivers his usual brand, but it doesn't stand the test of time. Between the infamous early head scene and the big confrontation ending scene, there is a lot of boredom, though some of it is okay. Some of the cast is a problem as well. Stephen Lack lacks talent and the more famous Jennifer O'Neill isn't much better and ludicrously looks like she stepped away from a magazine cover shoot. On the other hand, Patrick McGoohan overacts. I saw this when released and this was the first time I had seen Michael Ironside. He's rather effective here in a creep role that he would often repeat in his, thus far, whopping 282 credits listed here. The only other performers of interest here are Lawrence Dane & Robert A. Silverman in a small role. The special effects (all gore) hold up pretty well and for the uninitiated, this is a must for horror buffs.
