Interesting. I guess you might have had different opinion if you watched it while it was streaming. If you already had huge expectations, because so many people recommended it to you, I can see why you could be disappointed.
I watched Madoka as the new Maho Shoujo when it came out, because I just love Maho Shoujo. I had no idea what plot twists were ahead of me. And that's what was so amazing about it.
