I've read reviews where the execution is sloppy or that there were no noteworthy performances. It's up to one's preference whether those statements are true or not. However, the film does have a great message regarding what kind of drugs from Big Pharma you take and what kind of long-lasting effect they'll have on you or someone you love. It's done subtly and in the way Roger Corman dealt his messages. Plus, the music is top-notch. Which makes sense as longtime Alfred Hitchcock collaborator Bernard Herrmann did the score. Plus, the emotions are realistic and aren't over the top. It's not comedic like its sequels but dramatic enough to be taken seriously. I can only suggest you watch and be the judge for yourself. That way, you can decide whether you like it or not.
