I tried to watch Pewdiepie way back when I first found Let's Plays and I did not like him. It was the first video of his Cry of Fear playthrough and he was just so noisy and constantly editing bits out to the point where I got so confused as to what was happening.
Even now, I find him to be WAY too loud and obnoxious.
However, when has does his collabs with the other Let's Player I'm subscribed to, he's a lot better. Pewdie, I find is easier to handle in small, diluted doses.
