If someone dies, it's just one or two guys, and they eventually return anyway. Ultimatum had massive casualties, and there was no magical undoing of it. With only a handful of exceptions (Spider-Man, Captain America, Thor, Valkyrie, Dr. Doom), a big number of guys died and stayed dead. Good or bad, alternate or not, that was a crossover event that had to be made at some point.
As for quality, it is correct that it isn't the best thing that came from Ultimate Marvel. But it's not the worst from Marvel either. Marvel has produced things that were much, much worse: One More Day, The Crossing, Fearless, Absolute Carnage, Heroes Reborn, the Clone saga, Inhumans vs. X-Men, etc.
