Since I did a personal review of Equestria Girls when it came out, I figure it's a good idea to do another one for the sequel- Rainbow Rocks.
I'll be honest, I didn't hype up for this one very much. I watched all the mini clips that Hasbro released (3/4 made it into the movie and the 4th was referenced, so that was sweet) and saw the toys as they were released, but I didn't go into the theater with any real "plans" for the movie except one- and I was so excited when it happened EXACTLY like I thought it should! Maybe that's conceded of me, and I can't take full credit for it, I was just reading between the lines of what Hasbro put out.
Anyway, overall, a really good movie- better than the first. And it's very obvious that the first movie was more of a set up film which is pretty awesome. The three villains were fantastic. Hateful from the start and just so GOOD at being BAD. Sunset Shimmer has some amazing character development throughout the film, as do all the other characters- including Twilight (who is dues ex machina-ed into the film, but that's a very minor thing and not even a complaint at this point).
There were fun cameos of other characters (including a much more obvious nod to Derpy/Muffin Pony which was adorable and amazing) The music was all amazing- especially the songs the villains sing. Daniel Ingram did a FANTASTIC job using minor keys with their songs and they are delightfully haunting. Another awesome "Cafeteria Song" as well as quite a few others (I seriously recommend the soundtrack which you can find on iTunes)
Definitely a movie I'm going to get on Blu-Ray when it comes out.
I'll probably do a spoilers version of this review once I have a chance to watch it again X3
