It's pretty normal to be more bothered by casual violations of the way the world works than by fantasy elements. It's similar to the Uncanny Valley. With fantasy elements, our suspension of disbelief allows us to accept them as part of an alternate set of rules for the world. But when a part of the movie that seemed to be the same as the real world suddenly behaves differently, that can be off-putting and feel inconsistent. For example, if a character couldn't carry a small bucket of water but could carry a large man, many people would read that as an inconsistency rather than just accepting it.
