Don't go with the negative reviews, it's a GOOD MOVIE....and a LOVELY END TO A TRILOGY. The comedy good in all of the movie (except that one dance sequence ) ..the action sequences will make you feel cold and remind you of the old MCU. THE LAST 25-30 MINUTES WILL GIVE YOU CHILLS
I WATCHED IT IN IMAX 3D AND IT REALLY ADDED SOME GOOD POINTS TO THE MOVIE. But you should go nonetheless.
