The problem is the catalog is functionally infinite.

It narrows down significantly by region, for restaurants, and by time frame, for events.

Movies as a bit trickier, but you can ballpark that by genre and maybe "new releases" / "" / "criterion collection"

If you've got a big enough pool, you'll get plenty of crossover. "You just matched with a person who wants to go to a Knicks game, watch a horror movie, and dine out at Sopo Korean Eats" is going to get plenty of hits in Manhattan.
