Oooh thanks for your comments @happilybemused. I must agree Jersey comes off better than any of the characters (and it really is that beautiful in the summer!) although it is funny when they're walking down one street and then there's a jump cut and they're somewhere else entirely
It's fun seeing familiar places, they often film in mine & DP's favourite restaurant.
I agree, I think Tessa's ok. I saw her at a work event recently year and she was very 'on'; making eye contact, smiling and saying Hi to everyone (presumably just in case one of the strangers in the room could be of use to her one day). My friend has been to her house a couple of times for drinks and gets on really well with her.
I like the new Sarah/Sahra(?) a lot. I thought her naivety about the island was funny. I'd like to go for a night out with her. I'll work on it 
Karen I liked at the start but by the end I wasn't so sure.
Margaret comes across as really nasty & catty this season, but I'm told she's great fun in real life so who knows.
Kate I used to adore and have met a couple of times socially, but she recently got banned from driving for ploughing her car into a wall pissed, so all respect for her is gone. I have a few mutual friends with her Son and apparently he's a lovely lad, but he must surely be absolutely mortified by her?? What teenage Lad wouldn't be?
No strong feelings on Mia or Ashley really. I think it shows a bit that Ashley's locally born and bred; she's a bit more naive to the wider world than the others.
