Why is Romero Britto so scrutinized by art enthusiasts?

Every once in a while I come across a few memes in internet usually commented by a amount of people criticizing his works by not calling it art anyway. I'm not really into visual arts so I'm far from being an expert but I personally find it quite unfair to him and would add that good works are usually harshly scrutinized during the lifetime of its authors, until something 'worse' comes up next and people start to adore such artists, usually after they'd passed away already. What's your thoughts on his works and feel free to express any opinion about it too :)
