Finally got around playing it and kind of love hated it.
I like how they expanded on the consequences of your decisions (though explaining everything through a monologue is sort of cheap, it still worked), overall it served as a much better ending to the series as a whole since this time you actually know who survived etc.
However that's also the problem, before the extended cut, people made some wild speculations about how the next games could be very interesting with the whole new premise of the Mass relays destroyed and the various fleets all stuck in the Sol system. The extended cut obviously ignored that, and made it seem like everyone just flew home and rebuilt their homeworlds. ( I choose synthesize)
Though you can't really blame Bioware for destroying those theories because they just showed how they intended the games universe to progress, and I guess they would have never expanded on those theories anyway.
I have to nitpick one scene though. The Normandy landing right in front of the Reaper, picking up your wounded squadmates was freaking ridiculous. When they could do that then why didn't they drop all those people off with the Normandy in the first place?
And I guess when you're with Shepard you get a Limousine to drive you off the battlefield, the standard grunt doesn't even get a bicycle.
