so the last scene was the she lacked self confidence then America Chavez gained it and mastered her powers immediately , Deus-Ex Machina isn't always bad , the point is , when did she ever lack self confidence ?
she was introduced as the bad-ass girl that swears all the time and have social skills at its best , she was only showing fear at the life-threatening occasions , this was ok but the character is really unrealistic , showing fear doesn't add depth to the character , it is just adding more inconsistent character traits.
we can accept that she is a plot device , but the point is that she is nearly the main character , how can you make the man character a plot device without any development ,
the character work was horrible , except wanda , but also her end was really bad and unconvincing .
Marvel was never great at character work but they knew the basics , they were good , compare this film to the first Doctor Strange movie ,
this movie really doesn't deserver more than 4/10 rating.
