Sadly Nicktoons is reviving Voltron as "Voltron Force" and it looks pretty terrible. As in the horrid Iron Man and Speed Racer crap they put out when those movies first hit.
I'll reserve judgement on this one. It could be worse, they could be reviving the car Voltron or worse, the really bad 3 robot Voltron that merged into 1 robot with 6 arms. :rolleyes
For a while I know there were worries the movie lions would look like rejects from Bay's Transformer franchise. I remember a pretty lame revival of voltron in the late 90s or so. I kinda lost interest when it because super popular with rappers and whatever soda they used it in to sell.
