It's extremely popular, I would argue it's more popular than ever. Even the mobile game Dragon Ball Z Dokkan Battle was in the top 10 highest grossing mobile games in 2018, 3 years after its release, and that's no small feat if you look at how much the highest grossing mobile games actually make (a lot). The most recent PC/consoles game, Dragon Ball FighterZ, sold millions of copies in 2018. The movie has already grossed $33M in Japan since its December release there, and is breaking out in other foreign markets. BOM has it at $53.5M currently, so whatever it grosses in the US is just icing on the cake now.
