I beg to differ when, even though Leng was handled poorly, such a moment as this was full of Awesomeness. Some people believe that, but personally I doubt it. Then again, who knows, what with the Omega 4 Relay still in use by Cerberus, and perhaps whether or not you chose to preserve or destroy the base in 2 will have an effect on the mission. I'm just happy we get a 4th faction (Prothean Zombies, woo!), even if it may be confined to multiplayer.
