What the actual ****?
To the small minded people who have made similar comments to the one above, what's wrong with you?? It doesn't do any harm to anyone does it? Yes it might be a bit 'out there' and look odd, but so what?? Really, if they are happy then so what?!
Live and let live I say!!
The lack of facial expressions could be a problem for some, but for others, concealing their true identity can be a thrill, like the wearing of masks dating back hundreds of years ago to go to the theatre, festival, party, etc etc, even if the disguise wasn't always great (think of the Carnivals in Venice for example), to those who find it a turn on like in the film mentioned. It could even be out of necessity to hide some sort of physical deformity/injury - Phantom Of The Opera or a Pirate's eye patch anyone?
I just think it is an innate hard wired desire in the human nature of some to be something they are not/to deceive/to alter their body or appearance, be it with makeup, hair dye, a wig, a simple piercing or tattoo right up to, say, a sex change/or a delve into the unknown like that woman who looks like a Cat/Tiger!
Heck even kids like to enter this world of make believe and have their faces painted, dress up in old clothes, wear their Mum's make up etc etc, or wear disguises at Halloween, albeit for fun, but do you remember being disappointed when someone who wouldn't have known still recognised you behind your mask?
Yes there is sometimes a criminal element, but really, on the whole, GET OVER IT EVERYBODY!!
....... You could even more than adequately argue that clothing is a form of masking for a lot of people, and that it is quite unnatural in its own right!! (Despite the weather).
