"BioWare strongly believes in the team’s artistic vision for the end of this arc of the Mass Effect franchise."
They have received far more criticism for their 'endings' from long time fans than positive reviews, and they "strongly believe in the team's artistic vision for the end"? If I had a loyal fan base that told me something I did was absolute garbage, I would try to make it better, not tell them that they are wrong and give them 10 more minutes of garbage video. I do not care how much footage they cram in of Garrus or Tali standing on a uninhabited paradise planet, (which in a galaxy fighting for colony planets I found really wrong) or whatever patch they put on one of the gaping plot holes in this sinking ship of a story, it will not be enough. Point is, Bioware lied to us about the endings, got rushed by EA to finish, threw one ending in with poorly photo-shopped explosions and stock photos, gave Buzz Aldren a Klondike bar to read a few bad lines, and expected the fans to shut up and enjoy it. I bought the collectors edition of ME3, what had been my favorite video game series, but now I will not buy anything with the word Bioware on it ever again. Messing up with the ending is one thing, but their treatment of their fans criticism is not responsible or professional.
tl,dr analogy version:
If you went to a fast food restaurant and got a horrible burger with cat poo on it, they would apologize and give you a free burger, without any cat poo. Bioware would tell us to enjoy the damn cat poo, and release an explanation for the cat poo in a few months, while refusing to remove the cat poo from your burger. Meanwhile, they would defend their artistic choice of adding cat poo to your food, and charge you $10 more for lettuce and onions.
