In many cases reboots come in with unmeetable expectations. The charm of something that was enjoyed by someone years ago won't be replicated and they will be left disappointed regardless of how excited they were going in. Nostalgia is for the old, not the new version.
However with that being said....
Hate to jump on the bandwagon but Leslie Jones was indeed a terrible choice for the host. She doesn't have the charisma to pull in an audience. She is trying to make it more about getting her jokes in than injecting humor in the game naturally. Not that the original host was special but he knew to keep it about the game. Leslie should not be front and center. The game should.
We've been in an era for quite some time of overproduced contestants. "Make sure you're excited and good for tv." Price is Right in particular has been cringey for years in the current era due to this. Unfortunately here is another example. Most people's natural excitement have always worked fine for game shows. The artificial kind does not.
Reboots can be somewhat polarizing. Sometimes it's unfair. In this case however, the dissatisfaction is earned.
