Dark RP only for kids?

I might get tracked down and killed for saying this, but what is actually wrong with DarkRP? It's amazingly coded and alot of fun on serious servers. Sure, there are people ruining it and cancerous kids everywhere, but that makes the servers bad not the gamemode. Maybe it's just one of those things where people say that something sucks just to fit in or because they are scared of saying what they really think.
