Wait…

That's what all the fuss is about? I haven't beaten the game yet, because I can rarely play it, but I assumed the ending was total shit.

It's really because we don't know what happened?

I suppose that's something to be upset about, but still. If we've been following Shepard's viewpoint the entire time, I could find it okay that we don't know what he doesn't know. Maybe it's just my opinion, but the ending doesn't sound like the 'Don't play ME3 because this will ruin the series' thing that a lot of people are making it out to be.

I need to fly through the game real fast, to see what the big deal is.

I mean the Ending probably would have been better if Shepard had said this and died right there with Anderson while the Crucible went off and then see what happens at the end to see if all of your choices meant something.
