Nothing with Greivous in it could be OT-ish, Greivous is a character totally at odds with the OT. I very much doubt I would call any of this stuff OT-ish. The movie was even more prequelish than the prequels. I doubt the show could be so different as to be totally on the opposite end of the scale. Modern Hayden-based Anakin, anime-drawn kid, Jar Jar Binks, silly fucking droid troopers, overdone prequelish lightsaber battles, look-isn't-it-cool dark Jedi character, General Greivously Ill-Making... it's not going to be OT-ish.
