I'm happy with some of the changes they made.
Some of them were glaringly forced attempts to appease complaints. Like, the hilarious scene where harbinger patiently waits for the Normandy to rescue your squadmates.
A good deal of the many (MANY) flaws of the original ending were not addressed, such as the catalyst existing as he is (being the citadel, replacing abruptly an established antagonist, taking the shape of that one kid he couldn't possibly know about, lowering the dignity of the reapers, to list some more specific examples).
War assets still meant fuck all.
I still have several personal grievances with each of the endings, like the crucible's intended purpose remaining really obscure, the crucible's destruction wave targeting all synthetics instead of just "stuff shaped like giant crabs" for no reason, synthesis making no goddamn sense and essentially standing as "giving up to the reapers' way of thinking", and control forcing Shepard to ascend to a higher existence to beat the reapers as if the galaxy couldn't do it on its own merits, and the slap in the face that was the refusal ending.
All in all it was "eh...". I'm glad they at least spent resources on a free DLC for us, but I feel it was mostly for good PR. It may have been free, but keeping fans is still an investment opportunity.
I haven't given up on bioware, and provided they don't try to milk Shepard's story any more (IE move on to a new protagonist in a new era either past or future), I'll be more than happy to buy the next installment in the Mass Effect series.
