I’m not sure that lack of jeopardy was the issue with Furiosa – after all, that’s always the case with prequels.

I also don’t think that Day One introduced enough new developments to keep things interesting. The concept of the monsters is so simple that the main characters figure out the “rules” (don’t make noise) within minutes of the first attack. And that’s pretty much it - we, the audience, are none the wiser about what they are, where they come from, or what they’re about by the end of Day One than we were by the end of the second movie. Personally, I didn’t find the character development as interesting as Furiosa, either.

Either way, i agree that the quality of the story matters and I think Furiosa succeed here, personally.

If I had to hazard a guess, I’d say the differences in the box office outcomes come down to the facts that the Mad Max franchise has more of a niche appeal than A Quiet Place, is more violent, and the movie was quite a bit longer in duration.
