Here are my faves whom I watch quite regularly:

DarkChiron - A let′s player

Ashens - A comedian, reviews anything on his brown sofa

ChrisFix - A car fixer

AlChestBreach - A mod reviewer (I only watch his New Vegas stuff)

Adam Koralik - A retro game enthusiast

So who do you watch on youtube?

Screen junkies (honest trailers guys)

CinemaSins (everything wrong with... Videos)

Legolambs (does action movie musicals like commando the musical, dredd the musical, etc. In the voices of the main actors)

331Erock (insane guitarist that does theme songs for games and movies... Meets metal!)

Brandsins (made by guy who does cinemasins but with a different host, and they do everything wrong with various brands in the world)

Cracked (they have a lot of different things, some good and some bad. But they have some funny videos still)

College humor (just a bunch of funny videos. Some are really funny, some are not so funny)

ProJared: Love his reviews and gameplay videos.

Knightwing01: His Batman Arkham series are the best.

Cinemasins: I love their videos.

AVGN: He's mellowed out over the years but still puts out nice videos.

Lord Karnage (aka Classic Game Room): I like his video game reviews.

That One Gamer (aka The Completionist): Another wonderful game reviewer.

PeanutButterGamer: I love his Minecraft hardcoe series.

True Reviewer: He does some good top 10 list and other videos.

Channel Awesome: Nostalgia Critic's channel is the best on movie reviews.

Ashens: An Excellent Channel....https://youtu.be/Nsdg_j1r4aU.

Aqualung Game Reviews: Another great video game reviewer.

The Game Theorist: He does excellent theories on games.

HCBailly: He used to be one hell of an LP'er but his channel has gone cold these past few months, I'm getting pretty close to unsubbing to him. I understand getting burned out or getting depressed but damn man either make an update video for your fans telling them you're going to be on hiatus for awhile or close your channel, I hate it when a channel goes cold and stays active.

Lately i've watched https://www.youtube.com/channel/UC7_YxT-KID8kRbqZo7MyscQ scary game videos.
