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.
Macekre: This series is an early example of edited to hell and back anime in the States.
The Scrappy: 7-Zark-7 bashing is popular even among fans of BOTP.
Andreas Tomak, an original character from the Top Cow series, is not particularly liked either due to being a flat character who only serves to belittle G-Force and butt heads with Anderson. The fact he also took away paneltime from Zoltar was also criticized by fans.
They Changed It, Now It Sucks: Some opinions of the Top Cow series amount to this, as Munier Sharieff employed a darker tone in the BOTP canon in an attempt to make it more like Gatchaman. Jason's personality is one of the most decried points, with Sharieff depicting him as promiscuous, disrespectful to his teammates, and more of a violent loose cannon, with his overall attitude coming off as a Character Exaggeration of the original Joe Asakura.
There were also fans that took the presence of "Joe Asakura" as one of Jason's aliases as a Take That to the original Gatchaman, or as an unnecessary reference and confusing in its attempt to merge the two series' canons.
