How the fuck can anyone have a "coherent argument" about what films are good? Seriously, what the fuck is wrong with you, you fucking, fucking idiot.
The whole point of forums, film critics, etc...is that people express, wait for it ......THEIR OPINION!! Nobody here is an expert and everybody likes different stuff for different reasons. I just happen to believe that using characters breaking into song instead of using dialogue, whilst an interesting means of expression ...and one that has thrown up some good films, is not what we should be celebrating as the best examples of the best celluliod artistic interpretation or social commentary. I prefer films to be considered "the best" to have some basis in reality.
But that ....is just my opinion. Get over it.
