I thought most gave pretty good closure. I don't need to see how every character gets a happy new life after saving the world, an ending just needs to wrap the story up. Especially FFX did a good job at that if you ask me (and then they just had to go and milk it). Way better than FF8 anyway.

The ending of FFXIII is, like previously said, just pathetic. It's like they didn't even try to make it end good, as if the devs just said to each other "okay so this is the worst storyline full with plotholes we've made in a while, let's not waste any more effort on the ending either. Let's stop trying to come up with something and just fill it up with some eyecandy. It's not like they'll notice before it's too late, lol.".
