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.
Alternate Character Interpretation: The NCAA agent is right, and the Tuohys are exploiting Oher in order to make sure he plays for their favorite college football team. The scene where Kathy Bates lies to Oher about bodies being under the field at Neyland Stadium is disturbing on multiple levels, not least for the way it recalls the Stepin Fetchit, minstrel show-era cowardly black servant stereotype.
Ensemble Darkhorse: SJ. If the training montage doesn't do it for you, the college auditions sure will.
Sandra Bullock was adopting baby from New Orleans, who turned out to be an African-American boy named Louis, after Louis Armstrong. Made slightly less hilarious since she's divorcing her husband.
Michael Oher himself has been switched to right tackle, likely permanently, so he may never protect the blind side again.
The Drug Dealer played by Iron E Singleton better known as T-Dogg from The Walking Dead tell's Mike that "Ain't nobody gonna bite you."
All the lines about how the Tuohys didn't want Michael to play for Tennessee become this after he signed with the Tennessee Titans.
Hype Backlash: After it won Sandra Bullock an Oscar, audiences started seeing the movie in a bit harsher light, claiming that it won largely because of White Guilt, that the idea of a contemporary White Man's Burden film is uncomfortable, and questioning some of the plot points and acting as being narmy.
It Was His Sled: Michael succeeds at escaping poverty and reaching the NFL. Being a starter on a Super Bowl champion will pretty much spoil even non-sports fans.
Mary Sue: Leigh Anne can appear like one of these sometimes, especially when she faces down a drug dealer while searching for Michael. I mean, an unaccompanied white woman walking right into a Wrong Side of the Tracks neighborhood, threatening a drug dealer, and then walking right out again? Kind of unlikely in Real Life.
Narm: "Michael scored in the 98th percentile in protective instincts." It's supposed to come off as an example of her knowing what's best for Oher and standing up to the coach, but it comes across as awkward and prone to Fridge Logic (what kind of standardized test measures "protective instincts"?!?).
