Last night's episode was basically a horror movie, but not a good one.

they should just let Dany be full blown Napoleon

The ballista was a shit reveal. Westeros has siege weapons already. Is a ballista, which is designed for siege (i.e. an unmoving target) really going to help fight dragons? In the show's world, they can make it so, but it's pretty weak regardless.

The fan service on this episode was off the charts.

The chains are so people don't steal the books.
