Community's thing is that it is a meta show. It uses the meta it references to get a point across, make a joke, or provide a spectacle (a good example of spectacle are the Paintball episodes)

What OP referred to, and what I've noticed, was that media nowadays is just a mashup of what came before with little to say about it. Or to put it in other words: not transformative. The creator likes something, and they put it in their work because it's cool. There's nothing wrong with doing just that, but when you start seeing the same thing over and over again in different works, it gets tiresome.

We're so obsessed with filling every waking moment with something that we don't allow ourselves to have the "a-ha!" moment any more, so we default to "what if X and Y?" where X and Y are thoughts on the surface of our mind rather than two unrelated things that somehow click when the default mode network activates. For example: what do archways in a Shinto shrine have to do with a fox piloting a starship around? Absolutely nothing, and yet for Miyamoto that thought made sense.
