IMO the Stannis at the wall scene was dope. Ya'll forgetting that this 100,00 wildling army was more of a 100,00 caravan with women, kids, sick, and elderly making up the majority of the caravan. And not all the men (and women) were fighters and even fewer were capable fighters. Throw in Stannis' calvary and it's a fukking slaughter that would be over very quickly. That last man running towards Stannis and got ran down by the horesman is the perfect display of what kind of chance those foot soldiers stood against a mounted force.
Yeah, they kind of dropped the ball with more giants and mammoths but that's when the budget comes into play. That scene was doper than most are giving it credit for.
