I hate how fans and the fan base view Annie as the luscious blonde girl with bad luck even though this episode proves to us that she is so much more than that.
This episode under the title "Haunted" fixes many of the " opertion Wingman " episode's problems, including the superficiality of Claire's character and not giving her a lot of lines to say, or Annie's bad luck that almost turned into a really annoying thing.
This fact made Claire an outstanding, wonderful, and powerful character is so Great . For me, Annie is a genius in physics, mathematics, and psychology, with an amazing sense of humor that is strange, but really refreshing.
This episode does not have a lot of plot and that is simply because it is another one of the episodes of Generator Rex Filler comedy.
So the main goal is comedy, has it been achieved? Yes, strongly.
