Music
1) This is where I'm giving the most credit. Kajiura has once again done a magnificent job. I just can’t imagine the Madoka universe anymore without her works.
2) There are a number of new soundtracks; including the other two of which I haven't even heard so far. There are three -so far as I’ve counted- newly rearranged Sis Puella Magica(the main theme), two for Conturbatio(the Sayaka theme); one of those is a vocal version and played during the Sayaka vs Elsa Maria. It sounds something like an aria -like one from opera-makes the scene even more tragic. It is so heart breaking.
3) Credens Justitiam also has got a vocal version, definitely by Kalafina. You can assume how much Shaft cares about Mami.
4) The Homura vs Charlotte battle has got a new soundtrack, as well as the scene where Sayaka turns into a witch ;_; If you prefer Decretum, you might be a bit disappointed, although the new soundtrack is just as amazing.
5) EVEN WITCHES HAVE GOT THEIR OWN THEME SOUNDTRACK. Both Charlotte and Television-chan. the Charlotte theme is pretty nice. You can hardly wait for the release of the new soundtrack. I think there is one for Elsa Maria as well, but not sure if it was just the vocal version of Conturbatio which I have just mentioned above.
6) The ending theme is the movie arrange of Magia, at the full length. The new ending animation is, put it simply, an extended version of the original TV one, featuring silhouettes of several unknown magical girls before those of the main characters appear in the way like they did in the original one.
It was a so so cutee moment!! 
Wait!
watch to me!
