Well, IMO it's a great presentation both in terms of PQ and AQ. HOWEVER, it is a soft focus film and will come nowhere near the razor sharp clarity of Serenity.
So if you want the best presentation of a great film...Keep it!
If you are looking for 3-D and digital clarity (like Aeon Flux, Riddick, Serenity) then return it as you will be disappointed.
Also, see the Tier Thread for what others here think about many other titles...
