I just got home from seeing the movie. Overall I thought it was good. Not great, but it did clean up some things in the X-Universe. What I really want to talk about is the post credits scene. SPOILERS.
So anyone who has seen the movie and sat through the credits saw the end scene. A cloaked figure stands on a dune overlooked some chanting worshipers. The camera pans out and reveals that he is building the pyramids with his powers. Then the camera sweeps around and reveals his face. What was the reaction from the people still sitting in my theater?
The end credit scene on this movie left me with some mixed emotions. I think we can all agree that the purpose of a mid-credits or post-credits scene is to give a little bit of a tease for a sequel or another movie in the series. Marvel Studios is the master of this. They use these scenes to put a bow on the current movie while simultaneously introducing something new. Take Captain America: The Winter Soldier for example. The mid-credit scene takes us inside a Hydra base dealing with what happened at the end of the movie and also introduces the audience to the "twins". Fans of the MCU alone get something out of this and comic fans get a little something extra.
This seems to be my issue with the scene at the end of DOFP. I knew who the skinny blue guy standing on that dune was because I am a huge nerd. Someone who is unfamiliar with the X-Men outside of the movies has no idea who Apocalypse is. They don't know that he is En Sabah Nur, the world's first mutant. Although he is going to be the basis of the next film, introducing him this way at the end of the movie is pure fan service. The scene doesn't have any connection to the movie you just watched and will most likely leaving a non-comic fan scratching their head.
Fox should have once again taken a page from Marvel Studios when introducing Apocalypse. The way that Thanos was introduced at the end of The Avengers was perfect. A character that we had thought was in charge of the Chitauri invasion is seen explaining what happened to a figure in the shadows. The figure's face is then revealed. Comic book fans get to squee a little because they know it is Thanos and non-comic book fans are intrigued as to who this character is. The scene ties into the movie you just watched, even adding another layer, and it teases out something for the next movies.
