There are quite a few exceptions that Bell's theorem doesn't cover. In addition to superdeterminism, it doesn't cover the case where the measurement equipment becomes entangled with the system being observed (in other ways than making a measurement). In addition, if the universe is not strictly quantized and the appearance of quantized measurements comes about through certain "preferred" resonant modes determined by the structure of the universe, we would see the measurements predicted by quantum mechanics despite having only purely local state (seemingly violating Bell's theorem, but since Bell's theorem assumes a quantum universe it doesn't actually apply)
