No. This is a common misconception that frequently gets brought up that I would like to clear once and for all. ME3's ending was absolutely fantastic and it brought me untold joy.
You see, you made the mistake of assuming that a company mostly known for wrpg-themed waifu simulators would actually fulfill their promises in regards to having a living universe. Every single piece of evidence pointed against this but people wanted to believe. Every concern about another pile of corporate sludge speculating on barely legal marketing practices were dismissed as "contrarianism" or, my personal favorite, "hiding an anti-LGBT agenda." The series trudged on, selling itself out every step of the way, but people cheered every decision their neon god had made. Pre-release of ME3 was like watching mass-hysteria combined with thousands of fever dreams posted across all over the internet. Even the websites dedicated to small web businesses and IT contractors that I visited for work had a ME3 thread. I rented the previous two but pre-ordered 3; I wanted to be there when the bubble burst.
And burst it fucking did. I slamma-damma ding donged my through on casual difficulty and watched true beauty unfold. The dev team did not even ATTEMPT anything good. Pure, unfiltered sewage danced across the screen, the climax to god knows how many hours on the previous titles on Insane difficulty. I found myself laughing unto near-asphyxiation, tears and snot running down my face, chest heaving feet stamping as I beat my chest as what was left of my reason was convinced that if I didn't keep beating my lungs I would choke and die. For I had been right, absolutely completely right. By the time of the "moon scene" I had recovered enough to have clear thoughts again. "Ah, so this is how it all ends. With some half-assed 'b-b-but the moon people knew of the PC's sacrifice!'" I don't recall, at that time I had already forgotten which colour machine I had picked. It was over, finally over, but the reaction of the faithful on the internet was still unpicked - and ripe for harvesting. I was glued to my seat, salivating, anticipating the joy ahead when "It" came. For ME3 hadn't ended, not yet. It was -
Breath sputtered out, leaving only grunts on my lips as every pore on my body opened up, heart rate racing as the most powerful ejaculation in my life ROCKED my body to its core. I had gone from nearly composed and flaccid to a catatonic state ruining my clothes in a heartbeat. With the last of my strength I wrenched myself up and ran towards the computer cackling like a madman - if there was anyone else present at the scene I would have been committed to a mental institution in a New York Minute - only to trip and fall on my still throbbing cock.
You say ME3 had a bad ending; it did not. The most physically pleasing event of my life may have just ended but the paroxysms of mental joy were just ahead - on social media and forums, numbers untold. I rate it higher than the 2016 election for pure schadenfreude.
