We watched based on word of mouth praise from friends. Unlike most series of this type, thinking that we were "getting to know" the principals was an enjoyable alternative to the usual spy and shoot'em up thrillers led by Cruise, Craig, Arnold, et al. The guest cameos helped, too.
I hope that Donald Glover and the other producers are willing and able to produce a second season, depending on what happened with the three flashes of gunfire that ended episode eight.
