Scientific theories are rarely accepted immediately. Even if the evidence for a theory is impeccable, there will be some stragglers who resist it for lack of understanding. More interesting is when a theory that ultimately turns out to be true is legitimately resisted at first due to lack of evidence. (For example, for a very long time atoms were rightly not considered a known fact, even though there were many who vigorously argued in support of them.)

Newton's laws of motion now seem "pretty obvious," but that's only because most of us were taught them so long ago. What kind of resistance did they meet at first, and what were the most legitimate counter-arguments?
