Books vs Films

I hate being late to a film, part of it is because I hate trying to find a seat in the dark. But mostly it's because of the trailers. I love a good trailer. I particularly love those trailers that make you wish you were seeing that film instead of the one you're actually about to see.

The Wolverine had some great trailers; Thor: The Dark World, The Hobbit: The Desolation of Smaug, The Mortal Instruments: City of Bones.

I became strangely aware that I really, really want to see City of Bones. It looks amazing. It's hard for me to say that because sometimes part of me wants to punch something when I think about that particular series of books. And I don't fully understand why.
I think it's because I know it's history i.e. it's Harry Potter fanfiction origins. But while I am all for fanfiction, it irritates me no end when the word 'muddies' is mentioned. (Muddies. Short for mundanes, The Mortal Instrument's term for humans. C'mon, it really is just a poor rip-off of 'muggles.' Does that annoy the hell out of anyone else or is it just me?)
