Watching for the first time/opinions on the girls

I am watching for the first time and am on season 2. I see a lot of people talk about who they do and don’t like and I’m always shocked. Meredith, heather, and Whitney are my favorites. Mary Cosby is just a crazy person and I love to hear how her mind works. I absolutely cannot stand Jen and Lisa. I know Jen is pretty universally disliked especially after her arrest but I just do not understand how people like Lisa Barlow. Her strongest friendship coming into the show was Meredith and she is an awful friend to her, especially with her aligning her self with the shamazing shascammer. If you like Lisa, genuinely explain it to me.
