It's hard to argue with analogies, but I'll give you mine.

It is more like the guy who can paint very good landscapes would start criticising every oscar category from producing to sound design, telling that they have 0 idea what they are doing, and he would do it better. "Why the credits of Transformers are 5 minutes long with hundreds of people, you don't need more than 50 people to make such movie"... This is how Blow often sounds to me.
