Technically self defense does not bother me, just it is the content in it, even in self defense it still presented in a bad-guy cheese horror light that just deepen the reasons fans that did not like the turn the put Wanda threw in the movie just add on more baggage to that. It still has not held Wanda back though for being likely the most desired and talked about Character in the MCU right now in good ways, so that is good to know this has not slowed her down.
But such things like these are hardly should be around and it leading to quesitioning even more the depths of how disturbed the creators of the film where trying to go or just how off they where showing themselves in how much they accutually too from Wanda's Character history, which seems to be little to none showing a lack of work and caring that creators should have to avoid the justified backlash they got.
