AITA for jumping my 'friend' when she said she didnt like Serial Experiments Lain?

Let me just start this off by saying-I am the number 1 serial experiments lain fan!

Serial Experiments lain is a show made in 1998 about a 14 year old girl named Lain finding the "wired" (internet) and it completely taking control of her life. (watch it.)

So, I made my friend watch serial experiments lain and she said it was "hard to understand" and "stupid" and me, being a big fan of SEL (serial experiments lain) took huge offence to that! so I beat her up. 

but now there are police at my door and her lawyer emailing me. I don't think I'm the a hole but lmk...
