Let Me In doesn't change anything major to the plotline to Let The Right One In, but instead respectfully reshuffles some details and culturally rewrites itself for its American audience so as to give them an easier window of perspective. This is a good example of a remake changing itself so as to be better understood by another audience, as well as be better understood in general.
While the original was beautifully haunting, it danced around a lot of details and didn't firmly solidify the divorced nature of Oskar/Owen's parents, or the relationship between Eli/Abby and her caretaker. While it's one thing to let the performances of your actors organically drop exposition throughout a film, it's another to leave such important themes vague in the telling and then expect the same payoff as you would in a better developed story. The makers of Let Me In didn't pretend the other film didn't exist, nor did they succumb to "stupid American syndrome" and overtly spell the whole film out for domestic audiences. They made a good film great, and that's what all remakes should aspire to do.
