I have watched this film at least 50 times and I never tire of seeing it. It's proof that Cronenberg was, even nearly 20 years ago, a visionary with a strong stomach. The exploding head, the ruptured veins, nosebleeds and spontaneous combustion should have produced a film whose violence is completely tasteless, but it didn't. Instead, the director uses strong photography, an interesting notion for a plot (Cronenberge studied as a biochemist, and many of his films deal with the concepts of disease and infection) and a gripping soundtrack by his long-time collaborator Howard Shore, to build a film which is truly enjoyable. Despite the uniformly wooden acting and appallingly weak dialogue, the 'kinda' happy ending and a rather obvious 'right versus wrong' storyline, the overall effect is still gripping and - somehow - great fun. Great.
