I just got back from this movie. Man the movie was a lot of fun! People were cheering from the music that played at the beginning.
Then of course, the training montage, more people started cheering and that was a great scene.
I won't spoil the fight, but it was as great fight with a lot of emotion, and I liked the camera work (it looks like a real boxing match on tv, not a hollywood fight). THere was one point in the fight where everyone in the theatre just started clapping and cheering (and if you saw it you know damn well what part it was).
If you liked the other Rocky movies, you have to see this. It will bring back a lot of memories and emotion from the older movies. I have to say this is the first movie I've ever actually clapped in during the movie, and I had to actually catch myself and stop lol.
