Was the ending perfect? No.

Could they have done other things better? Yes.

Honestly, I found it pretty disappointing. I was good with it right up until she opened the portal. After that it was just so… quick. It all just suddenly resolved itself like POOF and then.. oh… she faded away. Oh… ok. The last scene was really good, though. But overall I felt like they could have done the bittersweet angle in a less rushed way.
