This was a great movie. Second only to The Martian as far as 2015 in film and second only to the first film in the Rocky series. I thought it was way grittier and not as saccharine as Rocky Balboa. Jordan and Stallone gave outstanding performances. Rocky's moment with Creed in the locker room talking about everyone he's lost was heartbreaking.
I liked how there was closure to Apollo Creed's storyline as a whole (Rocky admitting how guilty he felt about not stopping the fight in IV and also revealing the outcome of the fight at the end of III) with plenty of room to keep moving the franchise forward.
As a side note, I am relieved that picture of Stallone on the steps in Philly when they were filming was only makeup to make him look sick. The guy is almost 70 and he's still built like a tank.
