Between Dolby Cinemas, IMAX, RealD 3D, and Regal RPX there are a lot of ways to watch a movie. And some movies like The Lion King are released in all of them. But which of these premium formats is better? Well, it depends on you and on the movie. If you want the biggest screen size you can get, you want IMAX. But if you’re an audiophile you’ll love Dolby Atmos. And different genres lend themselves to different formats. A comedy is probably fine in standard/digital. But if you’re seeing a big blockbuster you might want a format like IMAX or Dolby Cinema.
