Lets not dog pile TGS for not liking the manga. You can disagree with their opinions without resorting to personal attacks or just ripping into them.
That's not really what they're arguing. The main issues I've seen is mostly just
- Extreme amounts of bloat or redundant material (Sage Centipede and Melted FU for example)
- The manga elbow dropping the reader with statements that Garou's actually a good person
- The mind control and time travel aspect just generally ruining stakes since almost no story does them well
- Multiple extreme redraws that change the plot heavily and result in even more redraws
I've never really seen anyone complain about Tornado being slightly nicer or Garou murdering people, the issue is that they tried to keep the twist from the WebComic but weren't subtle about it.
