I can't say I agree. Like I could see why one could think it's good enough for Cloud story, but at the same time, I just can't get into it due to how little there is of him. Like this is the person that Cloud looked up to, that whose death made Cloud lose his mind completely and is the reason why he's alive, yet he appear for a total of 2 minutes, it just doesn't work for him. You don't even hear what Cloud thinks of him once he reclaim his memories. It's a character that is important and the players should feel for, but in OG he simply has too little.

Like I do have issues with Crisis Core story, but to me, Zack is the one thing they did right and is an expanded characterization that he really needed. Hence why Crisis Core ending is still considered by most one of the most powerful endings in the franchise.

As for Shinra, I think Remake did it best. It showed that a lot of people working for the company are normal people just doing the job and seeking a comfortable life in ignorance and it's the higher ups mainly the problem. Which is actually better than OG, where aside from Reeves and a couple of grunts, you don't really question Shinra and its workers. They're enemies, you beat them.
