I find them funny. People take it way too seriously. Heck, Cinema Sins did a "everything wrong with Cinema Sins" video which was rather entertaining.
Don't know if I can post it because of the cursing but the director of Kong Skull Island and Kings of Summer went off on CinemaSins
Part of me thinks he had a good point (he pointed out where CS was flat out wrong) and that must be very annoying but at the same time it's comedy
