I've seen one video, about his top ten worst pokéballs. The guy seems like he has no humor, no sense of game-design, confuses the games and the anime, and doesn't know what promo-items mean. Anyone else who would have thought twice about the points he had written down would not dare repeat them, yet he said all of them like they were the most factual and profound truths to ever grace this earth, all the while sprinkling bad, unfounded jokes over everything.
It was enough for me not to bother with any video of his again.
