It got mentioned on Kermode/Mayo the other day...
that a kid had just watched and enjoyed 5-Armies and was excited that finally he could watch the LOTR-Trilogy. They commented that that was the way to watch them as he is going to love LOTR even more. Then they used this to refute comparisons to the Star Wars prequels, as they felt watching those first would make a kid not want to watch the OT ;-)
