For those who don't know Doug Walker is the created/owner of Thatguywithglasses website which hosts reviewers. He's famous for the Nostalgic Critic.
Right now he's watching ATLA for the first time because he has been asked to review the Last Airbender movie as the Nostalgic Critic. He doesn't want to watch the movie before seeing the series (which is good because the movie would probably scare him away from the series.).
I thought I share these vlogs because he has good insights:

Warning he uploads new videos to the site first before youtube. I'm not sure when he posts the youtube channel, but I know other youtubers post his stuff on youtube.
