Story: I'd say the biggest letdown is the story; the main plot has been done before. On the plus side, there is considerable effort put into the side characters' stories that helps add to the overarching plot.
Art: Another iffy spot. At times, the art is gorgeous. Other times, the art is very simplistic and "lazy". I think that the CG implemented into the show is a bonus, rather than a hindrance. While it is noticeable, it is well-done and very smooth.
Sound: I've watched both the dub and sub, and I love them both. Every character has the perfect voice actor attributed to them. The background music was hit-or-miss. Most of the themes are great, and have a very 40's jazz / golden age feel to them. Akin to the music of Pixar's The Incredibles.
Character: The reason I fell in love with this show. Everything from the designs to the personalities is spot-on. While Kotetsu is my favorite, it is very hard to pick a second favorite, or even least favorite character. Almost every character goes through noticeable development, and they become even more endearing.
Overall: A decent story backed by an incredible cast of characters and diverse themes. The show is equal parts action, drama, emotion (I connected with Kotetsu's storyline a lot) and comedy.
TL;DR 5 words/phrases to desribe Tiger & Bunny
great characters, funny, emotional, good action, hot men :)
