Samuel L Jackson Upstaging The Monster
I think by them putting popular stars like Samuel L Jackson and John Goodman in it they steal the attention from the Skull Island lore.
They've been planning to make a Skull Island for a while off separate Skull Island stories that they've had in print and comics before. I think them having Samuel L Jackson narrating in the commercial all loud booming and in his bravado 'Pulp Fiction' voice makes it seem more like a Samuel L Jackson movie instead of putting the main focus on Skull Island.
