Opinion on them? I hate them because 90% of then are boring, repetetive, have all cap titles, and have misleading titles and thumbnails. The only successful person who can think off the top of my head actually does funny, original, and actually tries really hard on his videos is Nigahiga. But, let's say Smosh, they aren't as funny as they used to be, have all cap titles, and misleading thumbnails. For examples, FOOD BATTLE 2011 or HOW TO COVER UP A MURDER.
Special thanks to TheArchfiend for exposing them for me!
