If you can't walk properly, but need to walk across from point A to point B, then use your crutch or wheelchair if you must. Heck there's this thing called hoverboard, it looks retarded but it has this gyro-thing that helps stabilize your lazy a**. Or there's this thing called VR, lets you do everything in a virtual 3D world and lets you reach the imaginary point B, C and beyond while walking in circle in real life. Doing nothing but it felt like you're doing something.
Trolling aside I think for simplified style it doesn't really need to be criticized as much since it should be given that the artist isn't trying to impress you with anatomically correct figure or anything like that. Just simple story with simple storyline. I even thing more people should stick with simplified style corresponding with their current drawing ability.
For realistic or semi-realistic style however my visual sense will be pushed on so many wrong buttons whenever I see bad arts. If that style is their goal, like that is what they what to portray to their readers, then they should learn an anatomy lesson or two. Appreciate that someone even cared to tell you of what you need to improve on.
Then again I've seen so many bad art critics out there. They'll say the shoulder looks off, that one hand is a bit longer and so on while the core issue is at more fundamental level. The artist clearly doesn't know his anatomy telling him to fix that arm or that leg or whatever is just treating the symptom, not the illness.
Even worse for action poses, sometimes the critics can't even do proper gesture drawings. Imagine you're the artist and you get all of this advices coming, how would you separate the good ones and the bad ones when you're still clueless on what's what?
