When it was first released in 1987, Predator didn’t make much of an impact with critics.

Reviews and fans alike loved the action, but, at the time, many felt the plot left much to be desired. But 30 years later, the tide has turned, as many of those same critics now hold up the original Predator as a standard bearer among action films, considering it among the best movies of the 1980s.

Three decades after its release, Predator has remained a force in pop-culture, staying relevant with multiple sequels, spinoffs, and comic books.

Even though there have been some misfires—Alien vs. Predator (2004) and Aliens vs. Predator: Requiem (2007) were both critical duds—Predator 2 (1990) and Predators (2010) were both well-received, and that’s created excitement for the next installment, The Predator, set for release in 2018 with Shane Black at the helm.

Fans are eager to see what Black does, as he has some major sci-fi fanboy cred after appearing in the first Predator as an actor and directing Iron Man 3. Boyd Holbrook is coming in fresh off his fantastic appearance in Logan as a bionic-armed villain, while Olivia Munn is bringing her ass-kicking skills to the cast after appearing in X-Men: Age of Apocalypse.

The excitement about the new film has gotten fans interested in looking back on Predator, which hit its 30th anniversary on June 12, 2017.
