This app is pretty good overall. Its like Netflix for Marvel comics, with a huge back library. Comics are added about 6 months after they hit the stands. If you have a good internet connection (better than DSL, obviously) the loading times are EXTREMELY quick, and you can queue up up to 12 books to download in the background and read offline. I see why they did that, its the reading equivalent of streaming video.
Now, the bad parts. Sorting the comics in your personal list is TERRIBLE. You can only sort by release date. Good for crossovers and such, TERRIBLE for reading whole series.
The ability to re-arrange things in your library like you can in apps like Comic Zeal would make this app PERFECT.
