Just finished this edit and it is as good as everyone is saying. It is the best TV-to-movie edit I have seen so far.
It really did feel like a movie. At no time did I get the feeling of missing anything. The edit also didn´t feel rushed. There were character scenes that took their time and set-up the consequent action nicely.
The new music fitted in almost perfectly. There were only one or two places (e.g. the execution of Ned Stark) where I consciously noticed the changed music.
I´m really looking forward to enjoying the next GoT movies.
