I really don't care for making Kong scary. Despite the classification of Kong as a monster movie, I never really thought of him as one in the scary sense.

The 1933 Kong was simply a big horny ape. He wanted Ann and that was basically it. The 2005 film aimed to bring a greater depth to the relationship of Kong and Ann. Here, they're two lost souls that meet one another and as strange as it may be, they truly understand one another. Most will probably agree that their relationship is the strongest aspect of the film. It's the movie's heart. Without, it'd just be reduced to any other bombastic and brainless movie.
