Why Does DreamWorks Keep On Making Trolls Movies If They Don’t Make That Much At The Box Office?

DreamWorks has made a lot of successful franchises/movies that typically do well at the box office. But one of them, Trolls, is one of their newest franchises, currently having 3 movies and a possible 4th upcoming. But something that I noticed is that these movies don’t do anything exceptional at the box office and barely make that much money. The first Trolls movie released in 2016, and only made 347 million dollars against its 125 million dollar budget. So Trolls didn’t flop per se, but it did kinda average, especially compared to a lot of other successful animated films at the time. DreamWorks then made a sequel, Trolls World Tour, that released in 2020. The film was a massive flop at the box office, only making 48 million dollars compared to its budget around 100 million dollars, but makes sense since it released around the pandemic (and probably did fine from streaming). A 2nd sequel was made, Trolls Band Together, and released on 2023. The film also flopped at the box office (albeit not as much as its predecessor), only making 209 million dollars against its 95 million dollar budget. So the Trolls movies aren’t really any big box office hits, but why does DreamWorks keep on making more Trolls movies and making the franchise one of their frontline if the movies don’t do that well at the box office?
