If a person says cameras using same technology has more cinematic look, but the same person can't even tell the difference between RED and 7D footage, then yes.If you write people off based on this kind of simple misunderstanding then I fear you have less of an open mind than you portray yourself as having.
You do remember him saying that him not seeing the difference between RED One and 7D footage proves the point that 7D is more cinematic than 5D?
