Chris McFeely is one of the best. Don't know if he's done any dumb shit in the past (as far as i know, he hasn't) but his videos are great. Even if you're a hardcore Transformers autist, his videos have clean editing and his voice isn't ear-piercingly loud, no retarded shilling and straight to the point. Usually his videos are a structured retrospective of the characters. Sometimes it's about a certain concept in the Transformers, such as cybertronian physiology, lore, factions or about a series. Occasionally i watch RodimusPrimal and he's decent. I do tend to keep a large distance from Transformers youtubers who vomit out political trash or defend certain faggotry (late IDW comics and Earthspark).
