I am confused how this got positive ratings... Sure the anime was cool, and the 3-D mech fights were pretty good (though nothing particularly special), but the plot was embarrassingly bad. Now noting that I only made to episode three before giving up,mostly because the main character is a relentless (insert demeaning word or phrase here).
Many people would accuse me of not having gained the whole experience because this is like putting all your opinion on a video game having just played the demo, but something in the plot should hook you in to make you dive in and enjoy it, the only reason I made it to episode three was because I was hoping that it wouldn't be incredibly cliche with poor writing and unlikeable characters. By no means are the use of cliches bad, you can utilize them and make it interesting, but creating a character who from the start you want to poor his entrails in a blender and make him drink a colon smoothie, is not the best way to create the main hero, especially when he declares "I AM THE HERO OF JUSTICE" while causing more property damage than everyone else combined.
But I digress, I suppose each person has their own opinion of good anime, this felt neither fun nor good in comparison to other anime in the Giant Robot Genre, such as Gurren Lagann.
