Revealing mistake: During the opening title sequence of every episode, for a brief second, there's a shot of the Sentai actors in the group morphing sequence shot. Evidenced by the fact that all of them are of Asian decent, lighter skinned than the Power Rangers actors and only one of them is female when there should be two.
