I think that's oversimplifying it a bit. There's a reason they say you don't want to see how the sausage gets made.
One of my biggest memories from when I first moved to Orlando was talking to a former Disney CM. She asked, "Do you like Disney?" I said yes. Her response was basically, "Then don't work for them, because the magic will be gone."
She wasn't disparaging Disney. Her point was that once you look behind the curtain and see how decisions actually get made - the compromises, budgets, politics, etc. - some of that shine disappears. The same can apply to Universal.
That said, knowing the finished product missed the mark isn't the same as knowing from day one that it would. These projects and the decisions behind them are usually a lot more complicated than that.
