Where did I say the problem could be solved by more power to the player?
Up top, by saying the lack of power fantasy destroyed the suspension of disbelief.
I would've been fine if the credits rolled with Shepard bleeding out just before they hit the button to activate the crucible. That would have been heart wrenching and full of pathos. To go through so much toil only to fall dead at the finish line. It would have been beautiful.
Ah, a cliffhanger that literally doesn't end the cycles and literally railroads the player-character into failure.
Instead, we got a magic elevator ride to introduce us to a new character we didn't need
Not a new character, more a plot device. The collective intelligence of all Reapers. Not far removed from Avina.
explaining things that didn't need explaining
Oh, are you one of the Lovecraftian /Cthulhu mystery believers who thought Sovereign's exposition about order and chaos, technological paths they desire, and systematic cycles weren't baiting an explanation?
by a nonsensical cutscene
Eh.
And to put a cherry on top, they got Buzz Aldrin to do a voicover and completely wasted him!
He's responsible for a cutscene that proves everything turns out just fine in every Mass Effect ending. Wouldn't call that "wasted".
