Season 1 was great. It was in the summer and would usually finish around 7 pm my time.
But it was also the most stressful. My power went out during a challenge and my phone almost died, I got delayed at dinner parties, I was doing a challenge during a job interview, and a flood almost all knocked me out. I was lucky I made it as far as I did.
I think the changing times, while feasible, also complicated things a little too much. That's why I am going to go back to the season 1 format of 9 PM EST.
