Y2k is a movie about the turn of the century, and the fear that computers would stop working due to coding only having two digits for saving files, and years up to 99 would work, but 00 would cause an error, which would cause computers to fail. This movie takes an original turn on this idea; instead of everything shutting down, technology develops a mind of its own, and tries to take over civilization.
From a viewer’s standpoint, the movie was decent although it it relied a bit heavily on classic slasher film scares, like excessive blood and gore, and a jump-scare or two. But movie critics heavily dislike it. Rotten tomatoes rates it at 44%. Audience reviews disagree for the most part; many of them claiming to be in high school around 1999, which led them to relate to the characters for the most part. The movie really was mediocre to me; most of the references were understandable, but I agree that it did rely a little more on the old slasher film tropes. Most of the thriller aspect was just violence. There were no jump-scares, and in my opinion, it was more of a “scary movie (2000)”-like movie, which really just makes it more of a comedy than a horror movie.
On a personal level, my parents were around that age range in the late 1990s. They thought the many references to Surge Cola, early Nu Metal bands, and pagers were both appropriate and hilarious. From my point of view, I also found them funny. I’ve been told many stories about the 90’s- how different America was before technology got more advanced and the many tragedies in the early 2000s.
All-in-All, I would recommend it; it’s entertaining for the most part. Just some of the overdone tropes ruined some of the more horror-centered scenes. Overall, I’d rate Y2K 3.5/5 stars.
