While Double Decker! took longer to grab me than Tiger & Bunny did, I immediately saw much of what I liked in Tiger & Bunny present in this show. Colorful and downright exuberant character designs, with even the more somber characters visually striking. A world which felt flushed out without having to tell you everything at the get go. And, while the emphasis is largely on Kirill in the first three episodes, a solid cast of characters.
I'm glad I stuck with it long enough to get to the ensemble and see Kirill starting to grow up a little. The plot really picked up in episode five, and I hope to see it pay off as time goes by. Tiger & Bunny astounded me in its ability to turn around and suddenly shift into a really well-written plot, so I have my fingers crossed for this one.
