It’s not bad but Congee is pretty much peasant gruel like grits or porridge. If you go out of your way to try it just set your expectations correctly lol
Sounds like you haven't had good congee, or it just isn't your thing. It can be amazingly delicious and is a great comfort / cold day dish.
Grits are good. Congee is rice porridge. It’s good.
I expect goodness and all these deliver. No need to explicitly set expectations, unless one is completely uninitiated.
