The Mass Relay in Arrival exploded because of the massive amount of energy it was constantly storing couldn't be controlled anymore once the structure gave out. In the ME3 ending, I think the Crucible used that energy to do whatever you made it do. But I agree, even so, the fact that the Citadel was destroyed, that you don't know for certain what happened to anyone but Joker (the old man in the epilogue, I presume), that the turians, salarians, asari, krogan, quarians etc. who fought the final battle on Earth will probably be stranded on it regardless, and a bunch of other things I can't remember right now really ruined the ending for me...
