The thing that was good about this show, and why is isn't so good anymore ...
The best thing about Real Time is the format of the show. It WAS light, informative, comedic, and serious all at the same time. The thing that made it work was that although Bill Maher expressed himself at the end in New Rules, funny and seriously and very well, he did not dominate the show or intimidate the guests or in general behave like a boor.
Somewhere in the last two or more years Maher began crapping all over his own show. By that I mean he would get angry at the audience, and he would focus on certain issues like wokeness or politically correctness, but in a way that was not from the everyman's perspective, but filled with his own feelings that started getting really weird about the time he turned 60, or started talking about how he felt old.
Instead of letting the guests talk it was all about finding common ground with the guests, which turned into and really meant finding ways to get the guest to agree with him, and he would get quite nasty about it too. You see, the show worked because Maher, I thought, recognized that everyone has their own reality, their own "silo" as they are called today, and he would bring people together do that the audience could get the benefit from the guests' perspectives - and it worked really well.
Somewhere along the time it became all about him expanding his silo so instead of the guests feeling free to express their different points of view, it became about Bill approving or disapproving of what was being said, and week after week pushing his own repetitive and often boring and factually incorrect ideas. The show has become a irritating experience now and I only end up watching it because of habit and to see what might be echoes of its former glory.
Also an odd think seems to have happened since Trump. Although Bill makes fun of Trump and insults him, over time he has taken on unabashedly Trump-like characteristics. I think Maher is cracking up or has early onset dementia to not be able to recognize this ... or maybe he does and just doesn't care.
