The amount of screen time Mance has is in line with his appearances in A Storm of Swords, which are memorable but pretty minimal.
In the books, the first time Jon sees Mance he approaches the gruff Tormund instead because Mance is a campy bard and not what he expected a warrior to be like. In the show they KEEP Jon mistaking Tormund for Mance but it's completely pointless as it's just Jon mistaking a gruff guy for... another gruff guy. I have no fucking clue what the point of that scene was in the show.
In the book, Mance expresses sadness for Halfhand's death. In the show he's delighted and offers to shake Jon's hand for it. The character is completely dumbed down.
We're going to get two more years of Cersei and Margaery exchanging veiled threats before anything actually happens between them.
In A Feast For Crows
, Margaery isn't a schemer. Cersei's insanity, motivated by Maggy the Frog's prophecy, leads her to assume Margaery is an ultra-manipulative schemer when she's really not up to much. In the show.. Margaery is exactly what the ultra-insane Cersei thought she was in Book 4. They've completely missed the point, so it won't be nearly as interesting. Cersei will come across as sane and rational.
