I don't know about any protests and I don't care enough to stop watching it.
But embarrassingly enough I actually watched all the seasons of Curb a few months back and finally decided to try the Seinfeld. I was expecting it to be the usual sitcom routine but I shouldn't have prejudged it esp considering Larry's sense of humor.
I think I was in your shoes too. I remember watching some episodes of Curb Your Enthusiasm, then I stopped for some reason. Then I watched Seinfeld and continued watching Curb Your Enthusiasm after.
