While I see the resemblance, I don't think it's so bad. Besides, I think it's rather refreshing to have a mentor figure that's an actual in-the-flesh extraterrestrial (and not just a head on the wall like Gosei). We haven't had one of those since SPD. I usually don't bother when they air episodes online early, but I might make an exception this time. BTW, RangerCrew has uploaded a bunch of clips from the first episode on one of their Youtube channels.
