I watched it yesterday!
It's very well deserved.
Though its pretty funny in terms of timelines. I think the movie is in a Marvel universe timeline, but the timeline is not the same as the X-men movies, wich have their own (2 actually).
I also loved the writing. It was amazing seeing the first faithfully written Colossus in an X-men movie. Deadpool was also very well written. It felt exactly like a comic book.
I don't know how they are gonna pull off Cable, but fingers crossed.
As much as i like the X-men. I wish marvel could take the reigns of it again to make all these movies make sense in their overarching universe.
