I'm exactly the same. My friends who dig monster movies tend to be the guys who had reptiles as pets. No idea why, but it was always the same people.
But I feel anything over 10 feet ceases to be relatable, though the original Kong is the one exception. It's just amazing.
When I see a giant thing versus a giant thing my brain switches off. You might as well see clouds fighting.
That said, I'm game for Skull Island and have heard great things from pals.
