Personally, I thought the ending was good but unfinished. Why? Well, allow me to comprise a small itemized list.
1. The Mass Relays. At the end, no matter what your decision is, the mass relays go kaboom. So how does everyone get back to their home planets? And considering how the last time we blew up a mass relay it ended up destroying a star system, doesn't that mean that everyone is dead? To me, part of the appeal of Mass Effect was exploring the different star systems, so how do we get to them now that the mass relays are kaputsky?
1a. ADDENDUM: The Citadel is now above Earth...so how do they get it back to the Serpent Nebula?
2. Closure for everyone else. I know a rough stab can be taken at what happens to Liara (goes back to being the Shadow Broker), Javik (goes back to his homeworld, makes a monument and kills himself) and Tali (goes back to Rannoch and leads the Quarians alongside the other admirals), but what about everyone else?
3. Why what happened? Were all of Shepard's surviving crewmates on the Normandy and they landed on...somewhere. Why? How did they end up there? What planet is it? Do they make a utopia multi-species planet? Do they all die?
4. How is Shepard remembered? He saved just about everyone, so what do they do to thank him? Do they make a statue in his honor? Do they declare his birthday "Shepard Saved Our Asses Day?" And what impact does Sheps' death have on his/her romantic partner?
5. Where did Shepard send the Reapers in the paragon ending? I would assume he sends them to the galactic core where they're ripped into atoms by black holes, bit again, who knows?
