Dimension W - not sure about this show, but the setting is interesting enough to continue watching. The best I can describe it is as a less-edgy version of Darker Than Black (which I'd recommend over this however).
Nurse Witch Komugi-chan R - amazing effort, this manages to be much worse than the original show, which wasn't very good to start with. The point of the original was that she's an incompetent idol + magical girl with a fairly shitty personality (similar to Sailor Moon's bitchy moments, but with none of the redeeming qualities). So the entire point was that she's useless and she sucks, i.e. pathos. But in the new version they transplanted her to highschool, and made her an optimistic and popular upcoming idol with lavish CGI concert scenes. So they took the parody out of a parody, and what's left is a boring husk.
Saijaku Muhai no Bahamut - synopsis seems designed to make me not want to watch this: Lux, a former prince of an empire named Arcadia that was overthrown via a rebellion five years earlier. Lux accidentally trespasses in a female dormitory's bathing area, sees the kingdom's new princess Lisesharte naked, and incurs her wrath. Lisesharte then challenges Lux to a Drag-Ride duel. Drag-Rides are ancient armored mechanical weapons that have been excavated from ruins all around the world. Lux used to be called the strongest Drag-Knight, but now he's known as the "undefeated weakest" Drag-Knight because he will absolutely not attack in battle. After his duel with Lisesharte, Lux ends up attending the female-only academy that trains royals to be Drag-Knights.
