I'm enjoying this series although agree about how PG it all seems. The girls are all beautiful in their own ways, I do think Rosie is very pretty naturally and I don't mind a bit of the contouring and fake eyelashes and things but I find all the hair extensions a little strange. It's the footage of them being held out and brushed that gives me the creeps! 
It doesn't look like Zara has extensions, just lovely thick hair. Or are hers just better than the others?
I'm fast going off Alex. He seemed sweet to begin with but now just a bit desperate. I don't really like the guys all egging on him coupling up/kissing a new girl. It's too forced and Alex isn't strong enough to say 'nah I'm fine thanks, I'll sort things out in my own time with the right girl'. Maybe that's not the point of LI though!
Samira came across badly last night although I think the point she was making (that Alex and the new girls probably wouldn't naturally hook up) is correct. He doesn't seem a good match for either I don't think.
Eyal is the most boring man on the planet. He has a nasty streak, but not enough to make him interesting (like Adam).
Josh seems ok but that bandana round the head thing like a 50's housewife is very odd. He sort of pulls it off because he's attractive and on telly and they are all wearing ridiculous things but can you imagine that in your local wetherspoons?
