Issue 1, I don't see this work lasting a long while, in fact, if there's a novel of this it'll probably have anywhere from 50 to 180. This'd be fine but we are very starved for a longer lifespan work but frankly, we gotta take what we can get in this niche where authors don't understand that they could easily make a shounen, but with female characters and probably even make do with little to no romance cause have you tried removing romance from your filters lately?
Issue 2, a oversaturated setting of movie/tv entertainment industry... though frankly, we could probably ignore this as it seems a certain law makes things difficult to get similar works and that's probably an understatement, I just don't know what all the law entails.
Issue 3 like I said before there's a few other works I know of similar or shorter length that'd been a more... interesting to read adaptation. This work so far has nothing over other works beyond the art, however I'm 5 chapters in and that's potentially subject to change
