Final Fantasy XIII series sold over 10 million games, do they deserve it?

I'm sure Square-Enix would be somewhat disappointed with the total sales of the Final Fantasy XIII trilogy. First game was a major disappointment and you can probably see that in the heavy drop off of sales for the somewhat better sequel.

Final Fantasy XIII-2 restored my faith in the series a little, whilst nowhere near the top tier of JRPGs it was a fun playthrough with an interesting villain.
