Is that a problem though? The problem for me would be lackluster content and pushing out dozens terrible shows that producers do manage to push out on a yearly schedule. I much rather wait longer, for a better show. I actually believe it's an ad for a show if it has multiple years between seasons. It shows me, as a potential viewer, that the show prioritizes quality over quantity and that the IP is strong enough that the company producing the show is willing to invest in it that many years later.
