5e has both too many rules and not enough rules.
It has very specific rules in some places. Item interactions, many spell specifics, grapple, holding your breath, etc.
It has very lackluster rules in other places. Social conflict, item and spell crafting, metagame stuff like making your own class or species.
I think a lot of people playing DND would be happier playing a different system. Just not the same system for everyone.
