The cut ending doesn't make a disjointed story. The soundtrack recorded in mono is not nearly as bad as they might want you to believe (in fact I didn't notice at all), and the fact that I don't remember any "impossible to finish" quests is a testament to that if there are indeed any (which I'm not denying), it isn't as bad as people claim. In fact the worse problems this game suffers from are balance and game mechanics, but I don't see nearly as many people complaining about that.
But anyway, it's not a very smart thing to do to have an opinion based on other opinions. They could be exaggerating to make a point, you know. My opinion is that this game as it is now is well worth its full price, but again, that is my opinion. An informed opinion, mind you.
There is nothing wrong with having an opinion. However, there is definitely something wrong with borrowing other's opinion and making it your own.
