The end of the franchise?
It all started with disastrous OW, ever since the difference between the first Lego Movie and this title is getting slightly bigger - talking about percentages here, up until today it was slightly smaller than 50% and now it's slightly bigger. That's not a good trend. How To train Your Dragon 3 opens next weekend, that will surely take its toll, not to mention TLM2 is already competing with HTTYD3 in international markets so it's unclear TLM2 will be saved by foreign markets (Alita is also a solid international competition, not sure if it opened in Asian markets already).
This is WB's first 2019's flop. The problem here isn't just with the earnings. The problem are the reviews. The fact that they're good. If they were bad then that can be easily fixed by changing directors. At least then there's room for improvement. But with the current situation I guess the only thing that can be done is put the Lego movies on hold for a few years, hoping the new movie will be good and that the market will once again develop interest for that type of movies.
