Just my two penn'eth FWIW...
Radfords - seem lovely if bonkers (ironing? with 16 kids... really??), although some of the things the younger ones said were quite telling.
Salims - just horrible, that poor woman obviously expected so much more from life. Mr Salim is an idiot. I remember seeing them on TV a few years ago after their youngest was born and his attitude was awful. The midwive pretty much ordered him not to have any more for the sake of his wife's health and he poo-poohed her. I shall never forget him bursting into the bedroom, camera crew in tow, while his wife was clearly trying to hide from the chaos, in tears, face buried in the new baby. 
Sullivans - something very Duggarish about them. Isolated kids, strict religion, homeschooling etc. (Obviously nowt worng with homeschooling but it seems they're using it as a way of keeping their kids away from others). Saw them on TV last year and they mentioned not believing in contraception - I was surpised more wasn't made of that this time, i.e. they're not choosing to have so many children as such, they're 'leaving it up to God'. RE: breastfeeding comments upthread, I wouldn't be surprised if Ma Sullivan was bottle-feeding expressed milk on the show - just looking at the way they dress I suspect modesty plays a big part (this is purely speculation on my part), and that might preclude her from breastfeeding on TV.
Quite liked the Lewises, again saw them on a previous prog and I remember Dad coming down the stairs after trying to get everyone ready to leave with an armful of confiscated hair-straighteners
. Poor Chantelle though, she must've been terrified when her DD was born amidst all that drama.
Hanns - seemed nice enough although it's a pretty mad view on life to think that having another baby will 'get you back to normal' but to each their own I suppose. I wonder if Posy's worked out breastfeeding gives her time with mum she might not otherwise have...?
Haven't much to say about the others, here endeth the ramble!
