I’d heard of Jack Ryan, probably bc of the Tom Cruise movie, and I happen to have seen Reacher. Looks like at least the series called Bosch has 7 seasons, so even though I’d never heard of it it’s got some longevity (even if I was originally looking for something related to Hieronymus). But the one called Cross only has 1 season from 2024, so it seems pretty obscure to be including in a puzzle like this.
