Personally, I think it was MadMax Fury Road or the first time I saw Star Wars Episode 7 at the cinema. When I watched Episode 7 at the cinema on the first showing on opening night the audience was so excited you could feel it all around you and being surrounded by at least 150 fans of the series was just incredible, but Mad Max was just full of incredible cinematography that I was in awe.
Edit: I don't know how I forgot Rouge One, It was great every time I saw it. But the first mid night showing was just so good.
