This will be very short my friend. 2 mins. only... and it's enough to be spectacular. There's no real reason not to watch it. It will take 2 minutes of your time and your gonna be blown away by the amazing animation and color they put on that 2 min. 30th anniversary product. As you reading this review, go watch it on youtube, there's no real reason not to do it. Even if you don't like gundam, watch it it's spectacular.
Overall: 9/10 (no story, no character, one music, total fun).
