The evil boss: Janice (Lorna Scott)
The miserable employee: Wesley Gibson (James McAvoy)
The vile task: Dealing with abusive yapping, stapler snapping and her office birthday party.
Why he doesn't quit: Oh, he does, in a big way. Once he finally gains a little self-esteem (and some superhuman powers), Wesley snaps in an expletive-ridden rant directed at his boss.
