Is Batdad inappropriate for children?

So I watch this dude on Facebook known as "Batdad". He's ridiculously hilarious and his children are adorable. His parenting style and how he jokes with his children are seen as controversial to some. If you don't know who he is you can search on Facebook or YouTube "Batdad". I was reading some of the comments (big mistake, I know but most of them are highly supportive and Batdad responds to comments) and one person made a comment saying "Don't let your children watch batdad". Other parents were commenting about letting their kids watch Batdad, no problem. Most were preteen age, but some parents let their 5, 6 year old watch him. Thoughts?
