Of course the suspension is disbelief is somewhat contentious because religion also suspends our disbelief or doesn't suspend our disbelief.
For instance, Zeus and Poseidon don't suspend our disbelief, while Jesus and Mohammed do suspend our disbelief.
So we can judge not only art by the suspension of disbelief, but also religion.
But religions hate to be judged by this criteria for there are so many whose disbelief is not suspended by this religion or that, but only by their own religion.
They hate to be judged so much that will tell you, "Don't be judgemental".
