Well at least this one seems to follow the 1984 cartoon series with the look of the characters; bumblebee is a beetle and Starscream? is a F-15 jet fighter.
Is this a reboot? This movie wouldn't make any since other wise. If they did a proper reboot and made the series follow the 1984 cartoon series look I would be willing to give it a chance.
I have never heard of voltron and just looked it up. It was just the power rangers but 10 years before power rangers and cartoon. I don't know how I never heard of saw this before.
