The movie kicks off with a going-away party filmed by Rob (Michael Stahl-David). But the celebrations gets cut short when a massive earthquake strikes New York City, followed by a huge explosion. As Rob continues filming, he and his friends watch in horror as a gigantic monster tears through the city.With the monster attack unfolding around them, Rob sets out to find his girlfriend, Beth (Odette Yustman), who got separated from the group in all the chaos. The shaky camerawork can be a little difficult to stomach at times, and you don't get many clear looks at the creature, but that's also part of what makes “Cloverfield” so haunting. The footage feels eerily real, almost like a collection of recovered archival videos documenting what a real monster attack on New York would look like.Watch "Cloverfield" on Pluto TV now Follow Tom's Guide on Google News and add us as a preferred source to get our up-to-date news, analysis, and reviews in your feeds.
