See, if you look at it from this broad perspective without any details, this sounds like a fun anime romp with gears and robot girls that has the occasional Rule of Cool trope going on. Once you actually get into the series, however, the truth is far, far less attractive. The characters don't behave logically. It's rather common for the characters to do stupid things that are outside of their personality. Why? The show uses fanservice in place of character development. The laws of physics? Thrown out the window. And not in your typical anime fashion of people doing epic acts. Physics like clockwork mechanisms acting as a cell phones, and clockwork androids somehow heating themselves up when all their gears are stopped. Oh, and flat screen monitors that supposedly don't use electromagnetic technology. Why? Because this show likes gears. Gears for everything. Gears in places where they have no function. Gears where they already stated those gears shouldn't work. Remember that. If the character is acting incoherently, the answer is boobs. If the universe is acting incoherently, the answer is gears. What makes this worse is as you get further into the series, character abilities and motivations are not even explained! There is a whole conversation that Naoto has with the big villain at one part of the show. It gets referenced multiple times afterwards as part of how the characters act, and the villain keeps having flashbacks to it. WE NEVER SEE IT. We know it happened. We know a line from it. The rest is only for the ether to know.
