In my experience, MongoDB shouldn’t be used in cases where you need relations, or the typical guarantees that ACID databases bring. I think a lot of the “beef” people have towards MongoDB is from past experiences where it was used in this regard. I usually use PostgreSQL at this point, but when I use MongoDB, it’s more as a “document store” than a “database.”
