In terms of hosts, most of them were somewhat annoying.
Though I was willing to overlook the hosts' annoying demeanor/behavior, and watching the trainwreck antics of the guests.
(Without getting into politics).
Geraldo was hilarious every time there were shows on tacky topics/guests, such as: satanism, nazis, klansmen, etc ....
Same story with Jerry Springer, Wally George (ie. The Hot Seat), etc .... but with the guests beating up on each other.
The only "reality" tv shows I bothered to watch semi-regularly over the years, was America's Most Wanted and COPS. Back in the day, occasionally I also watched Jerry Springer and Geraldo.
