Harmy, I was looking at it the other day and I thought Empire looked amazing. Then again, you're the "creator" and will always see the flaws the rest of us missed. I'm sure you could be working on these the rest of your life if you wanted, but eventually you just have to walk away. Works of art are never finished, merely abandoned.
In any event, while Empire is my favourite movie, luckily it's also the SE that I find the least objectionable and don't completely hate watching.
