It's not but take a look at Xenosys or Arthar's when they criticize among others. They still enjoy the game, still play the game, are open to new things in the game and will be constructive. Zepla just whines, in her dawntrail playthrough you could tell she wasnt even willing to give the story a chance, she'd made up her mind and WAY overplayed her dislike of every single scene. It was pathetic acting.
Criticizing when you genuinely want to like the game vs when you have already decided it's no longer for you and will not like it no matter what happens come across way different.
