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.
Base Breaker: One of the largest ones on the entire site, to the point of being blacklisted on TGWTG Secrets and in the Secret Treehouse as of 2013.
Broken Base: As mentioned on To Boldly Flee's YMMV page, Hope's portrayal of Edward from Cowboy Bebop has earned mixed reviews. Shortly after the episode where she became Edward, Hope Tweeted that the ratio was around 70% in favor of it, with 30% disliking it. Funnily enough, this was long after she herself had noted in her review of Bebop that the character is extremely tricky to play without veering into being annoying.
The Witchblade review. When listing off differences between the anime and comics (in voiceover form with Nash, a casual fan of the comics, slowly becoming more distressed as they go on), the majority of the listed differences are not supported by the facts of the show. To be fair, however, none of her errors are things that are blatantly inaccurate, and one of them is supported by what's shown and said in the series until you consider that Masane is a temporary bearer, not the intended recipient of the Witchblade.
Her retrospectives on Digimon Adventure mentions that the series was meant to be only thirteen episodes, which has been long debunked in the Digimon fandom.
Creator's Pet: She is a mixed example (as she's regarded as being a good critic on her own), but this comes across primarily in her crossovers with other critics, especially in her review of Sucker Punch with Film Brain and Revolutionary Girl Utena with Kyle. Jesu throughout the Sucker Punch review physically abuses Film Brain (a rare case of Double Standard: Abuse, Female on Male for TGWTG), and her crossover with Kyle drives him insane (and is brought up multiple times afterwords). Also, while most crossovers have one person suffering for something (The Nostalgia Critic frequently being bullied, Todd chasing after Lupa until To Boldly Flee, etc), this never happens to JO, which is highly glaring.
Crosses the Line Twice: The Penguin Lottery wherein she broadcasted her game of Zoo Tycoon, creating an exhibit with 150 penguins and 5 polar bears, and had the people watching her stream bet on which penguin would survive the longest. Accompanied by Yakkity Sax.
The Legend of Korra fans got quite upset with her when she compared Korra to Anakin Skywalker to the Star Wars prequels and acted like you were just kidding yourself if you thought she was a heroic person. And then she called her a "cunt" the next week, which got even worse backlash.
In her Eiken review, Sage points out that JO would probably not have that much of a problem with it if the show were about a a cast full of muscular pretty boys in revealing outfits and with big...endowments, to which JO awkwardly tries to change the subject. Skip ahead a couple of years, and JO sees Free!...which is pretty much exactly what Sage described. And JO really did like it!note Although that's more to do with the fact that the show's writers are at least trying to give it a plot and three-dimensional characters along with the manservice than the manservice itself
