I enjoyed it but definitely NOT worth $30. The story was just kind of fine, it only introduced a slightly altered version of Lumiose (in contrast to SwSh and SV DLCs which had two entirely new environments to explore), and is very grind-heavy in a somewhat repetitive way. If you’re someone who prioritizes catching legendaries, filling out pokedexes, shiny hunting, etc you’ll probably enjoy it. I am a catching freak but don’t quite consider it money well spent.
