Great show. Really carries the superhero spirit, in some cases better than it's North American peers.
I certainly endorse this recommendation. Just beware of some anime conventions before you go in!
First: What i'd like to term as "cool down" episodes. These happen right after (and I mean right after) a very serious and dramatic story arc. Typically, they have very little relevance on anything... They just exist to provide some humor (or in some cases, fanservice) to lighten things up. Can be fairly awkward watching a show jump wildly in between tones.
Second: Fanservice. That is, butt and boob shots. They happen. Not nearly as much as some of Tiger and Bunny's contemporaries, but it's still worth noting. This shouldn't be anything new for people who read comic books.
