Well, as someone who agrees wholeheartedly with the poster of 23, I say that you should watch a few episodes and make up your own mind. However, if you're not a fan of Getta Robo, Voltron, Japanese Transformers, Mazinger Z or any of the other 1970s robot anime, you will miss most of the references. Because, yes, it is an otaku show.
Plus I think Yoko's outfit is pretty stupid for a gunslinger. The costume designer has clearly never thought about support. Even the Dirty Pair on duty wear more.
