I love Dan
At first, when my 6 year old daughter started watching DanTDM, I was pretty shocked and a bit annoyed. I don't have much of an interest in video games and didn't find any way to connect with him.
But then he posted a video about his hair color. And I got hooked! Dan is sweet, completely age-appropriate (he is aware that his audience is very young), and entertaining. His viewers learn about his pugs and his wife, and he presents as a positive role model.
We even bought a signed copy of his tour DVD. I think it's because I became such a fan. ;) Now my daughter has moved away from Dan and doesn't watch him anymore. I kind of miss him and hope she starts watching again!
**I'm editing to say that she never watched him play anything close to violent video games. We stuck to Minecraft and pretty tame games.
