WW1984 is certainly a turd of a movie. But saying it's Catwoman or Highlander 2 bad is the movie equivalent of people that think Alabama could beat an NFL team. Gal Gadot was at least occasionally charming, particularly when interacting with Chris Pine. Some of the Amazon stuff was kind of cool for a moment. Highlander 2 has essentially no redeeming qualities.
There are some very bad movies that on a technical level maybe could make that list like Battlefield Earth, Showgirls, and The Room. However, those movies have a population of people that enjoy them ironically or at least in a guilty pleasure sort of way which I'm not sure you can say about the 2 I mentioned.
