Franchises like the Predator are basically monster movies, where the monster doesn't talk and just consumes, kills, mates or whatever because its purpose is to be evil to humans. You can lump in that "monster" category things like Alien, Riddick, Godzilla, Jason Voorhees and Resident Evil. You're not going to get something like Killmonger (Black Panther), an evil force expressing some Shakespearean, conflicted character to create drama. What makes monsters movies fun is interesting kills that make you throw your popcorn, seeing how the humans outwit the monster, and whatever mythology they can build behind the monster. If they can do any of that well in this movie, I'll be happy! A streaming service like Hulu is sort of a studio, and sort of a distributor. It has a hand in creating or commissioning some original content. But it also buys existing content that someone else already developed and completed to sell to a distributor. I think the quality problem these days is that streaming services can pick up some very good stuff (say, an indie movie that got raves on the festival circuit) or some very bad stuff (like a big studio dumping onto streaming a movie it decided won't do well theatrically). The latter is basically today's version of direct-to-video titles from the VHS and DVD eras. Disney, which owns a majority stake in Hulu, has also tended in the US to put its more family friendly stuff on Disney+ and its more "adult" stuff on Hulu. Prey seems to have wound up being developed directly for distribution on streaming. Maybe the studio wasn't so hot on the financial prospects of the franchise for theaters.
