Yeah, I understand that obviously she can't succeed in anything she wants to do, but I would prefer if she were thwarted by the others do clever things to stop her rather than her own obsessive need to have the most convoluted plans, rather than just marching in and kicking ass.

It might help if she had any decent motive, too. This whole 'rightful ruler of Camelot' stuff is crap. There is no way she has any proper claim on the throne. I know she's crazy, but still. I'd respect her more if she just outright said 'I want to be queen for no good reason other than I want to be queen'.
