Machinima hate

So judging by the views of many in the lecture today nobody likes machinima, i can kinda see why in some parts but i disagree with many others. Using stock animations and models for something outside of the scope of the original game is foolish yes - seeing master chief in an embarrasing yet apparently humourful (not sure if thats even a word) social situation as he goes through a looping reload animation is so metally jarring it hurts, but when there used to further extend a games story or ethos it can only be a good thing, right? Much the same way fans write fan fiction for there favourite film or book machinima could be used for games.
Alot of the machinama out there at the moment is based around comedy and lets be honest all of its crap, its about as funny as you'd expect from a 14yr old living in Texas i can see parelles people draw with comics many people expect comics to be funny have some kind of punchline at the end of the three frames, raised on the sheltered antics of the Beano and the Dandy its hardly surprising - i struggle to think of any newspaper cartoon that isnt marely shallow humour and im including those shameful daily mail strips about footballers and girls with there tops off. But dig deeper and comics are a serious genre as grave and adult as there big brother, literature. Anyone who's read through Holocaust inspired Maus will testify to that - all monochrome and tiny frames crammed onto the page the thing oozes depression and dispair.
So why can't machinima try this approach? Get rid of all the damn linkin park music video covers and making something truly dark almost artistic? It was also mentioned in the lecture how using compuer models will never be as good as the real thing, well no they won't, thats uncanny valley territory there humans are very good at identifying a real human from a fake be it a real model or onscreen , even the very finest pixar models which take days to properly render look stiff and wooden which is why they often go for a more stylised cartoony look, think Incredibles. Look at the latest iteration of team fortress its clearly take a leaf out of the incredibles design book somehow the models look MORE realistic when they follow the design rules commonly used for more traditional cartoons.
If someone would take the time to create custom models for a given role, never seen before only used for the role in which you first see them with the props and enviroment matching the same design and visual look with an intelligent story and direction would it still be crap? I can see machinima becoming gamings equivalent of claymation - some of the more arty one's you never see in the mainstream are positively evil, brief visions that takes months sometimes years to create rather than constalty trying to twist gaming and the tool set that comes with it into something its not, in this case mainsteam films why can't they be something on there own?
