>>2323772Strengths:
The soundtrack- You would think a soundtrack that used mariachi music wouldn't work for an anime. But Sadimitsu makes it work.
The characters- They really shine. Half the fun is watching the thuggish Sadimitsu trying to get along with his sentient powered armor.
Weaknesses:
The plot is pretty cliche- A bunch of alien prisoners end up on earth, and through a series of events, the main character is the only one who can stop them.
The ending- The ending while fitting can be a bit bittersweet.
