Shockingly amoral, Formula 51 follows a “master chemist” (Samuel L. Jackson) who’s trying to sell a new drug to the highest bidder. If you think that makes for a questionable hero, wait until you witness the callous and casual cruelty with which endless characters are killed off. A bullet to the face is considered a punch line in Formula 51, but only the most soulless audiences will want to be in on the joke.
