I mean certainly against Universal's expectations it's a smash. It was estimated to open to $45 million opening weekend and it basically doubled that at 80 million opening weekend. You'd be hard pressed to find anyone in Hollywood that doesn't consider the film a huge success (especially given the pre-release tracking, the theatrical marketplace, and the fact that it isn't a superhero film, an animated franchise or Jurassic.
The international numbers aren't great but these are domestic parks we're talking about and the domestic performance is what Universal was directly concerned with anyway. It's in the top 5 films of the year and it's essentially an "original" screenplay despite the very loose tie to the original Twister.
All of that on top of the relatively small drops, the fact that it easily surpassed the domestic box office of other tentpole releases like Godzilla x Kong (which opened to the same number), A Quiet Place Day One, Bad Boys, Ghostbusters, Kingdom of the Planet of the Apes, Kung Fu Panda, etc. It was a certified sensation in 4DX to the point where they're re-releasing it in the format next week. It's Universal's biggest live-action movie of the year by far and will gross about $100 million more domestically than the last Fast & Furious film. If we can have a stunt show based on the Bourne Identity I think Twisters is on the table especially given how easily it translates into an attraction.
Will it happen? Probably not but it isn't because the film didn't perform.
