Every time I have seen the "dark phoenix" storyline I always found it almost a design by committee affair that ends up being too much, either because it is in and of itself or because it has to try to one up the last one.
Will probably be better than the time travel thing but doubt it will beat first class or Logan. On the other hand there is hope for a little action romp at least. I am probably supposed to be excited to see Professor X become the old man version of him but eh. I also have to wonder if game of thrones will be like star wars for any of the actors that rose up with it.
