Backing up a bit, the complaint that modern Trek is not "cerebral" enough tells me that it has enough action to attract a somewhat more pedestrian audience. As if bringing in people who aren't on the same intellectual level as existing fans will invade their space. New fans will dilute the gene pool, so to speak, and water down fandom so as to become mainstream,thus taking something away from them.
I call these fans Sheldons.
Star Trek is big enough for everyone. If you don't like the new stuff, ignore it and be happy.
"Cerebral" is what nearly shut Trek down before it started. Dialing it back is what made Trek what it became. Be glad for what we have and celebrate the fact that it lives after nearly 50 years.
Now, enough serious talk. I'm going back to making fun of people and looking for spoilers.
