That's why Anthem was a miserable failure. Players didn't hype it up or hate-watch, they just tuned it out altogether.
anthem failed because it was utter fucking shit at launch. there was enough interest from biodrones and normalfags that get swayed by pretty bullshots (and the tards who still pay for destiny and warframe would've been just fine with another space-y loot&shoot), but bioware couldn't even deliver that, it was battlefield 4 levels of bad, if not worse.
that's not how you launch a new franchise that's supposed to compete with an entity like destiny.
it's mostly fixed now, if they would've released in that state (which is basically just fixes and polish, it hardly got anymore content) it would've looked completely different. but then that's par the course for bioware, just look at TOR.
This series was doomed the minute EA added ridiculous production schedules and told Bioware to "tone down the nerd shit", and that happened with ME2.
that was bioware because dean takahashi (yes, the one of
cuphead fame) was too retarded to upgrade his shit in mass effect 1 and wrote a review about it.
as for ME2, most of it's faults could easily be ignored because it gave most people what they wanted - more space adventures while banging aliens. ME3 fucked even that up. that's why the most criticism you hear is about the beginning and the end. as you said, the setup makes no sense but it's easy to forget afterwards - till you fight the T-800 reaper.
I'm pretty sure this series was always doomed, ever since the Reapers were introduced. As cool as Sovereign was in ME1 (despite having very little substance and ignoring Shepard's questions that would have actually fleshed the Reapers out), the dark energy plot that's circlejerked so heavily very likely wouldn't have satisfied fans, either. That's what happens when you introduce Lovecraft-like villains, and outside of Bloodborne I can think of very few games that pull it off well.
reapers were fine, trying to explain them was where it went off the rails. you can't have your villain be "beyond comprehension", even if it was just written for
omg so deep wank, and then have their motives be completely mundane. the dark energy plot would at least have some philosophical depth to it where you could argue the willingness to kill off whole civilizations on the regular because there really is no other way is "beyond comprehension" (still not good, but miles better than OMG SKYNET).
but the smart move would've been to silently drop them for good and only mention them when necessary for the plot. the whole point of ME1 was that the reapers can't jump in directly anymore, it was all about postponing their threat, and not go "nah, it was just another year lawl". with the reapers looming in the background it would've affected the whole political and societal landscape, which would leave plenty of hooks for spectre or even cerberus shenanigans. but no, bioware needed another BBEG for the "press button something awesome happens!!1" crowd.
