Of course, the remake generally needs to be good to keep people sticking around past the first episode, but people were far more interested in remakes like MacGyver and Lethal Weapon at the start of the TV season than the were about a show like Notorious, despite some big names being attached, so it’s clear that having a well-known name has at least some merit.
Plus, let’s be honest, sticking 24 in front of a show name does help.
That’s why so many reboots, remakes and revivals are getting off of the ground these days.
Those sorts of projects already have a fanbase built-in.
