One of the biggest hair blunder occurred on Peyton Place in 1966. At the beginning of the episode Mia Farrow(Allison) had her long trademark hair with bangs. Later in the episode she has a short cropped haircut. In the middle of an episode, Mia became angry and asked for a pair of scissors in makeup. She began cutting off all her hair in a fit of anger. She was dating Frank Sinatra and he told her she could not come to his 50th birthday party because his ex wife would be there and it may come across disrespectful. Mia also wanted off the show and hoped this acto would get her fired. The hair tean had to fix her hair and a quick rewrite was done to write the new hair do into the storyline.
I find Isabella highly annoying, but I will allow the Izzy/John romance as being viable. One of my favorite scenes from the tale of 2 romans is when Marlena is talking to Abe and says you get to love them both I don't... All the tears for me. And when she tells John she loved him, loves him. I die. And then it fell off to nothing for about 2 years but it ended fine.
I never liked Kristen/John much. She was just so secretive and weird. ED and DH had chemistry, but Kristen never felt like a real option. He was still so clearly into Marlena.
