2D Animation sadly is hard and expensive and requires so much time to do "nicely". So of course Comedy shows would be what studios would turn to since they are simple to do.
That is why action animation and fluid animation are not something you see in Western shows because they are hard to do. Most Anime don't even do them right because of budget/time constraints (look at all the outsourcing done to Korea for Anime filler). All this is sadly why 2D animation is becoming a lost art, it involves a lot of time and expense for very little payoff. Again, it's why Comedy shows are popular in the west, they require not that much time/effort and thus can get a payoff with that little expense.
Until someone can invent a faster way to make 2D Detailed drawings animate well, you won't see much change.
