These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternative Character Interpretation: Did Curtis ever really care about either Effie or Deena, or did he just use them the way he used everyone else? If he had known that Effie was pregnant with his child, would he have still kicked her to the curb, or would he have tried to work out a situation that would work for all of them?
Artistic License - History: There's a scene where the Dreams are recording "Heavy", the shots before we actually see them recording is clearly of the Detroit "12th street" riot of 1967. There's even a small recreation of the event before we see them performing a rehearsal of Heavy at the television studio. The following scene, there's a brief shot of the marquee that states that the year is 1966, making the riot irrelevant to the plot (except to display the Civil Rights Movement that was appropriate for the era).
Award Snub: Most people felt Eddie Murphy should have won the Best Supporting Actor Oscar for his performance as Jimmy. Norbit caused him to lose it.
The movie earned eight Oscar nominations, more than any other movie of its year, yet got denied a Best Picture nomination.
Jerkass Woobie: Effie, not a jerkassper se still counts. Although she was selfish, rude, and self-absorbed at first, she loses her spot and her boyfriend, who she really wanted to stay with while she was pregnant with his baby. It's not that hard to feel sorry for her. Plus, seeing him getting married to Deena must have hurt her a lot.
